90 Day Korean Review – My Experience Trying It For 3 Weeks

Quick Review

Summary: 90 Day Korean is an excellent Korean course. The way that the material is structured and the simple manner that it’s explained make the language feel much less intimidating than I expected. In addition, having access to a personal coach that you can send questions and get feedback on assignments is a huge bonus. Split up into four 90-day modules, 90 Day Korean can take you from not knowing any Korean and get you to a relatively high level.


There are some small things that could be better but overall I was very impressed.


Very thorough without making you feel overwhelmed.


It’s a bit expensive but worth the cost.

I Like

The content is explained in such a simple and straightforward manner that it’s hard not to understand it.

From the first lesson, you’ll learn how the language works instead of just memorizing phrases.

Unlimited access to your own personal Korean coach.

The challenges really push you to apply everything you’ve learned and take it a step further.

I Don’t Like

You’re only given access to one week’s worth of lessons at a time.

There’s nowhere on their site that you can purchase individual modules.

The ThematicLingo lesson type isn’t very well-done.

Price: 90 Day Korean costs $47 per month. However, once you pay, you get access to that material for life. New lessons are released weekly, though you can also pay to access new materials faster.

Upon hearing of the name, 90 Day Korean, my initial reactions were something along the lines of, “There’s no way you can get fluent in Korean in 90 days. If that’s what they’re claiming, then it must be a scam.”

Luckily, they aren’t pretending like you only need three months to master Korean. In fact, there are four separate 90-day modules. Breaking a big course up into these small chunks makes it more digestible and less intimidating.

After all, becoming fluent in Korean is a huge goal. So, first setting the smaller goals like being able to have a 3-minute conversation in Korean, to order food in restaurants, take taxis, and write Hangeul are much more appropriate.

That’s how far the first module is designed to take you. Of course, 90 days isn’t enough to reach fluency, but it’s still a very important timeframe as that’s when you’ll set the foundation for the rest of your studies.

In order to write an in-depth review, I decided to take advantage of 90 Day Korean’s 30-day money back guarantee.

I tried out their first three weeks of content and although I don’t know much Korean myself, I’ve tested out so many different language learning resources that I know what is needed to make a quality product.

I’m also quick to say when a course is disappointing even when every other review claims that it’s an amazing product.

Take, for example, Rocket Korean. It’s highly praised, but not particularly good.

90 Day Korean, on the other hand, isn’t recommended nearly as often but is actually a far better course.

In this review, I’ll show you exactly what it’s like to use 90 Day Korean.

Course Overview

Screen Shot 2019 01 06 at 5.50.27 PM

90 Day Korean is set up a bit different than most courses. For one, although it costs $47 per month, it’s not a typical subscription where you lose access to the materials after your subscription ends.

It may be a bit more fitting to think of it as a course, where you keep the materials for life, but pay on a monthly basis.

Another important thing to know is that new lessons are released once per week. So, you won’t get the full 90-days worth of materials once signing up, just the first week’s. Most students are able to complete a week’s worth of materials in about five hours.

But, if you’re the type of student who has more free time or studies quickly, you can purchase the next month’s materials ahead of time. Or, if you’d prefer, you can purchase the full 12-month course by sending them an email. This would cost $47 x 12 months = $564, minus however many months you’ve already paid.

It’s a bit unique to release the lessons in this manner. They say that doing so makes it more similar to a university course, which does make sense. Having the material released weekly can also prevent students from just skimming the material and moving along too quickly without mastering it.

Another unique, and awesome part of 90 Day Korean is that you’ll have access to a personal Korean coach. You can message with them as much as you’d like. This is a great way to have any of your questions answered or get feedback on writing assignments.

Getting Started

Enrollments are open to just 30 students per month. After registering and paying for the first month, you’ll be hit with some upsells.

This caught me off guard a bit. There isn’t anywhere from their main site that gives you the option to purchase the whole 12 months in one go, so I was surprised to see it here.

I’m not sure if I’ve become jaded by bad products and offers that look like they’re selling too hard, but for whatever reason, seeing these sales pages gave me a bit less confidence in the quality of 90 Day Korean’s course.

Luckily, those worries didn’t turn out to be justified.

Their offer for the full 12-months with a 30% discount is actually a pretty good deal. And, they don’t seem to be like many of the courses that give you a “one-time” offer every couple weeks.

In my time using 90 Day Korean, I was never again prompted with a discount, even when I emailed to inquire about the total cost to purchase the full course.

Weekly Lessons

After registering and paying for the first month, you’re able to get started with the first week of lessons. This begins with a description of how to use the course and then jumping into their 90 Minute Challenge.

I loved this part. Starting with the 90 Minute Challenge really did wonders for demystifying the Korean writing system. This made everything much easier and worked as an excellent foundation.

In just 90 minutes, you’ll learn how to read Korean. The lessons are explained in such a simple way that it really feels like anyone could learn. They use a lot of psychological tricks to help you remember all of the sounds.

By the time you reach the end of the 90-Minute Challenge, you’ll be given a few words to read. It’s pretty impressive how quickly you’ll feel like you have a solid beginner’s grasp of Korean.

As I mentioned, I had previously tried Rocket Korean, and in doing so, never really felt like I understood Korean as much as I did from this short exercise.

This is the strength of 90 Day Korean. They break things down simply and teach you what you need to learn, right when you need it.

Moving past this lesson, the other lessons you’ll find in this first module tend to fit into one of the following categories.

  • Fundamentals
  • 80/20 Vocab
  • ThematicLingo
  • Challenges

After that, there are quite a few extra materials as well – but we’ll get to those later.


I believe the 90 Minute Challenge would fit into this category of fundamental lessons. These lessons require your full focus and teach critically important parts of the Korean language. They’re scattered throughout each week’s materials.

Some example topics include special vowel combinations, sentence structures, introductions, verb forms, and a lot more.

These tend to be somewhat dense topics, but they’re explained so clearly and straightforwardly that they feel rather simple. Often times, the descriptions can seem a bit silly, but they really do make things easier to remember.

Another thing that I like about these lessons on 90 Day Korean is how often you’re given questions to answer. These work as great ways to test yourself and see how well you’re understanding the material. You’re given the answers as well, so you can get instant feedback.

80/20 Vocabulary

The next common type of lesson you’ll find in the modules are the 80/20 vocabulary lessons. They’re meant to teach you the 20% of vocabulary that you need to know to get 80% of the results.

The process is laid out for you very clearly, but you’ll need to do the work to make sure you remember these words.

Screen Shot 2019 01 06 at 4.21.48 PM

First, you’re given a list of around ten words to learn, with an audio file to listen to the pronunciation, hangeul, romanization of what the word sounds like, and its meaning.

The following steps are all optional but definitely worth doing.

Next, you’ll want to make associations for each word. These can be anything that helps you to remember it. The stronger the associations you can make in your mind, the easier the words will be to remember.

An example here would be remembering the word for yesterday (어제) pronounced as “eo-je” by making a connection to “Yesterday, I drank OJ (orange juice).” Doing this for each word will take some time, but it’s also a very effective method.

Some words you may have no trouble remembering, so it’d make sense to just skip this exercise for those.

The next step is recognizing the Korean and being able to match it to the English for each of the words. You can click to see the answers afterward.

In the fourth step, you try to remember the English when given the Korean. Again, you should check your answers after.

Screen Shot 2019 01 06 at 4.38.05 PM

The final step asks you to write the Korean when given the English. This will probably be a bit hard to do as you haven’t yet learned to write Korean (that comes in a later lesson). There is also a lesson on typing in the Extras section. If you were to complete that first, you’d probably have no problem typing the words here.

Otherwise, it’d probably be okay to just write it as close to the original as you can but be somewhat forgiving if you make small writing mistakes.

Screen Shot 2019 01 06 at 4.42.21 PM

Finally, after completing all the exercises to help you learn the vocabulary, there’s a ten question multiple choice quiz. This works as a nice final way to check how well you’ve learned these words.

These 80/20 Vocabulary lessons are pretty common, with one or two each week (at least for the first month that I tried).


The ThematicLingo lessons are probably the least well-done of any part of 90 Day Korean. In these optional lessons, you’ll learn a bunch of vocabulary related to a specific theme. The lessons are named according to the topic, for example, JobLingo is about different jobs, and StudyLingo is about classroom items.

Screen Shot 2019 01 06 at 4.50.34 PM

You’re basically just given a picture with a lot of words to learn, and then audio clips where you can listen to each of the words.

It’s pretty disappointing.

Luckily, they’ve also made an Anki file (found in the Extras) that has all the vocabulary from the first module. I’d highly recommend using Anki as a way to review the vocabulary, so I’m really glad that this is included.

Another positive point is that some of the exercises found in the next “Challenges” part will give you opportunities to practice these words by having you practice writing sentences.


Challenges are a really great way for you to finish off the week and demonstrate what you’ve learned. This is a great time to fully utilize the personal coach that comes as part of your subscription plan.

Each week, there are a few different challenges included. They’re called missions and are written in a sort of fun way.

Screen Shot 2019 01 06 at 5.07.15 PM

This is a good time to get some practice writing Korean, become more comfortable forming sentences, and practice the vocabulary you’ve learned. I like how it really ties together the different pieces that you learned throughout the week.

The fact that you can get feedback from a real person is a huge benefit as well.

These challenges create a really rewarding feeling of accomplishment. Being able to learn so much in a week and then use it like this feels great.


When you get started with 90 Day Korean, you’ll get access to the first week’s materials, along with the extra materials for the whole first module.

These are all optional to do, but I found them to be really worthwhile.

In total, there are 15 extra materials included in the first module. Some examples are the anki decks to help you memorize Hangeul pronunciation and vocabulary, learning to type and text in Korean, getting a Korean name, using the Naver dictionary, a beginner’s guide to asking questions, and three ReadnRight lessons.

I can see these ReadnRight lessons being a great way to take your Korean a step further.

Screen Shot 2019 01 06 at 5.24.42 PM

You’re given several sentences. First, you’re meant to read them to understand their meanings. You’ll then read them again while listening to the audio file to make sure you know the correct pronunciation.

It’s also useful that they’ve color-coded each of the words. Green are the words you don’t know yet, red are question words, blue are vocabulary words you’ve already learned, and the black words are markers that you’ll learn later.

Screen Shot 2019 01 06 at 5.28.35 PM

The second step is to respond to the questions that are asked. Doing this will get yourself speaking aloud and putting together the Korean that you’ve learned.

Screen Shot 2019 01 06 at 5.30.42 PM

In the final step, the conversation has been filled in for you. Here, you’ll read the conversation, then listen to the audio file and mimic the speakers.

All of these ReadnRight exercises are really useful and effective for practicing multiple skills. I’d highly recommend not skipping past them.

Is 90 Day Korean Worth It?

I think 90 Day Korean is a course worth paying for. I’m impressed with how manageable they’ve made learning Korean feel. The simple and clear explanations really can provide you with a great foundation.

Although I’ve only tried the first three weeks of lessons, I would assume that the content remains as consistently well-done throughout the duration of the course.

Because of this, I think 90 Day Korean could be a great option, that’s not only good at the absolute beginning of your journey but even as you reach an intermediate and higher level of Korean.

The $47 monthly price tag is somewhat intimidating. Luckily, it’s not like most subscriptions where you lose access to the materials if you stop subscribing. It’s more like purchasing a course in $47 monthly installments.

The fact that they offer a 30-day money back guarantee can ease the stress of trying it out for the first month and gives you a chance to make sure it’s a good fit for your learning style.

Additionally, it may be smart to take advantage of the one-year discounted price that you’re offered when paying for the first month.

Overall, I came away really impressed with 90 Day Korean. The lessons are structured in a way that they naturally build upon what came before. They manage to teach a lot, without going too slowly and making you feel bored, but still simplifying things enough that you don’t become overwhelmed.
