Why Use 90 Day Korean?

Most of us pick up a second language as a hobby, but there are a lot of other reasons why you may want to learn Korean.

Moving to Korea

If you’re thinking of making an exciting move, it’s probably a wise investment to spend a bit of time learning some of the basics.

If you’re coming from the West, the difference in culture can sometimes be a little intimidating.  As well as the language, it’s essential to understand the cultural differences between these two very different worlds.

Korean Houses

90 Day Korean is a fantastic resource for this, as not only does it help you speak the language, but gives you insight into exactly what it is like to live in Korea.  Not only that, but they provide you with a complete rundown of everything you should do before you go.

Check out these blog entries for a tonne of valuable and free advice.

Love of Korean Culture

Korean Culture is hot property now.  You only have to look at recent blockbuster movies (ParasiteTrain to Busan), Netflix Shows (Kingdom, Itaewon Class) and of course KPop Stars (BlackPinkBTS) to see the popularity of all things Korean.

BTS also recently launched their own language learning lessons on the Weverse app, which we reviewed earlier this month.

Korean Culture

Learning a language is a fantastic way to understand a culture on a deeper level.  90 Day Korean, as well as teaching you the language, help you to understand the Korean culture much better than any other online method we have tried.

You can trust us, we have tried a lot!

Friendship & Dating

90 Day Korean has an excellent forum where you can interact with tutors and fellow language learners.  Not only do they provide help and advice in relation to any language questions you may have, but it’s also a great way to make friends and meet new people.


We all know the importance of practice in a language routine.  By speaking with new friends in Korean, your ability to maintain the knowledge you have learnt is drastically increased.

And you never know where a friendship may lead!  One of my friends met their partner on a language exchange app, and the rest is history.

Perhaps you already have a Korean partner.  Getting to grips with their language will enable you to communicate in a much more natural way, will help you to understand them better, and give you an excellent foundation for a long and healthy relationship.


K-Drama Fans

You may have noticed the recent influx of Korean Dramas, better known as K-dramas, on Netflix (check out this top guide if not).

If you’re not getting a regular dose of K-Drama goodness, you’re seriously missing out.

As well as giving you a unique cultural context, watching shows in Korean will help build your language skills.

90 Day Korean provide a psychological approach to learning Korean, which will allow you to immerse yourself in a worldwide phenomenon, even without subtitles!

K-Pop Fans

We can’t make this list without at least mentioning K-Pop.

Many of the students we speak to want to learn Korean for their love of the music coming out of Korea.

K-Pop Boyband

K-Pop is fun, engaging and quite honestly, unlike any other music culture in the world.  It also helps students with their pronunciation, their listening ability, and a way to pick up on a more natural way of speaking (by learning local slang!)

The benefits of being able to understand song lyrics are obvious, and 90 Day Korean will help you to do that, without the need for translations.


Korea is open for business!

If you’re someone who regularly travels on business trips to Korea, have some Korean colleagues you speak to regularly, or even want to take the first steps at getting a job in Korea, 90 Day Korean can give you a boost in the right direction.

Seoul Train

Best of all, learning on the go is made easy through their app, so even if you are constantly travelling for business, you’ll have no excuse to not put in the practice.

The 90 Day Korean Course – An Inside Look

Now for the best bit – the course itself.

In case you didn’t know, the goal of 90 Day Korean is to have you comfortably hold a 3-minute conversation.

Now 3 minutes might not seem a lot to you, but given that most of our day to day interactions outside of our family or friends, is just a few minutes, this is plenty!  3 minutes is enough to order a coffee, tell a taxi driver where you need to go or ask for directions.

So the main course that 90 Day Korean Offer is known as the Inner Circle Course.

Let’s take a look inside to see exactly how it works.

How to Get Started

After you sign up, you’ll be sent a personalised welcome by the team at 90 Day Korean.

Follow the links to the exclusive content locked away in the Inner Circle.

The Inner Circle Course

The Inner Circle course is divided into 4 modules, with an extra module containing exclusive bonus features.  Each module represents a ‘step up’ in terms of your Korean ability.

Each module is broken down into around 12 weeks and further into lessons, to create an easy to follow format.

I know what you’re thinking.

Wait, it’s called 90 Day Korean, and what you’ve just said means there’s a years worth of content.

Well, yes, you’re right.

The aim of 90 Day Korean is to help you to hold a basic conversation, which, if you follow their well-structured plan, you can achieve in 90 Days!

If you’re a beginner, module 1 is where you will start as that is where you will learn precisely how to maintain a 3-minute conversation with a native speaker.

What’s in Each Module?

Length: 90 Days
Aim: Hold a 3-Minute Conversation

Designed with a beginner in mind, at module 1, you’ll start out with the basics.

In module 1, you will learn how to order food in restaurants, tell a taxi driver where you want to go, ask how much something is…you get the idea.

Module 1 is where you’ll also master the Korean Alphabet (in fact, you can start this right now without subscribing, by following this link.)

At the end of the module, you’ll know enough to have a basic conversation in Korean, and be left with a massive sense of achievement!

Well done you.

Length: 90 Days
Aim: Build on your new knowledge

So you’ve mastered your first 3-minute conversation, give yourself a pat on the back.

But it doesn’t stop there.

Module 2 helps develop and expand your skills further.  Let’s face it, the 3-minute conversation you just had was a little broken and awkward right?

Module 2 introduces tenses, tonnes more lessons and valuable content to supercharge your abilities.

Check you out!

Length: 90 Days
Aim: Understand the culture

In the third module, you’ll learn a lot more about Korean culture.

Now, this module is relatively new.  It was added after 90 Day Korean received a lot of requests from students to add something that would help them understand their favourite K-Pop lyrics, watch their favourite K-Drama without subtitles, or just get to know the local lingo.

The ultimate aim was so they don’t sound like…well a foreigner.

90 Day Korean even claims after the third module, you’ll become an “engaging Korean extrovert!”

Length: 90 Days
Aim: Become a Korean master!

So after 9 months of intense studying, you’ll end up at module 4, but there’s still work to do.

Module 4 helps you understand the quirks of the Korean language, enabling you to become a charming Korean speaker, perfect for use in the office or classroom.

Once you’ve reached this level, you will have completed the 90 Day Korean course, congratulations!

But with extra modules added all the time, your work is never over!

90 Day Korean regularly update their content to ensure you are getting the best value for money.

The extras module is packed full of additional content to help you on your way to fluency.

Inside you’ll find some excellent materials including Anki decks, memorization tips and tricks and a wealth of other resources to help with your studies.

Each of the 4 modules unlocks additional content to complement the main lessons.  The extras provide you with a tonne of extra information to practice what you have learned and hone your newly acquired skills!


Completing a Module

At the beginning of each week, a new week of lessons will become ‘unlocked’ in your Inner Course dashboard.

You’ll receive an e-mail to let you know you have new content waiting for you.  Better get to it!

As you work through each lesson, ensure to mark them as complete. The feeling of marking off a whole week of lessons is incredible and will keep you motivated for what next week has in store.

How Long Do I Need to Spend on Lessons Each Week?

To make real progress, and to achieve a 3-minute conversation after 30 days, you will need to spend 3-4 hours per week studying your new language.

Thankfully, the way the course and content are structured, 3 hours is entirely achievable.  The content is designed to be engaging and fun to use, so 3 hours will fly by!

Practice Makes Perfect

As you progress through each module, you’ll be given plenty of opportunities to really firm up your newly acquired knowledge through practice exercises.

Remember that the method behind 90 Day Korean is the 80/20 principle.  This principle states that 80% of the language we use on a day to day basis is actually formed around 20% of the vocabulary.

The practise exercises reinforce this principle by allowing you to drill in the basics.

Typical exercises include:

Example of exercises in 90 Day Korean

You also get access to PDF worksheets for use alongside the exercises which you can print to use on the go.

Hit the Korean Gym

Time to get your sweat on!

One of the coolest parts of 90 Day Korean is the Korean Gym.  Small bitesize lessons in easily digestible chunks.

The Gym is where you’ll go to learn specific vocabulary centred around one topic.

If you’re looking to expand your vocabulary on the weather, animals or even technology, you’ll find the Korean Gym incredibly useful.

The best part is that these mini-lessons are regularly updated, so you’ll always have content to go through when you don’t feel like hitting a full lesson.

My Korean Coach

Without a doubt, this is the best feature of 90 Day Korean.

If you compare the cost of either a private language school or even other online programmes, the programme offered by 90 Day Korean is extremely affordable.

If you elect for the Full access course, you’ll receive full access to a personal coach.

When you first join, your coach will send you an e-mail to welcome you, and also to set some all-important goals.

It’s essential to be both honest and realistic in your goal setting, as your coach will help to keep you accountable, but most importantly, smash your goals!

Your coach will also be on hand at any time to answer your questions.  As far as we know, there is no other course on the market that does this, which is invaluable for a new learner.

Live Training

The team at 90 Day Korean have recently launched live training sessions, where you can get together with tutors and fellow learners for group activities.

These live sessions are usually focused around a particular theme and are a chance for you to practice your speaking skills and perfect your pronunciation.

All lessons are recorded and available in the members area for you to catch up on at any time.

The best part – the live training is open to all members, regardless of membership level.

The 90 Day Korean Community

90 Day Korean - Community Page

One thing we really loved about the 90 Day Korean platform is the active and engaged community.

The community has an open forum, separated into topics, where you can go to ask specific questions (if you don’t have a coach).  You can even use the community to meet new people, socialise and make friends.

There are subforums dedicated to a wide array of subjects, including K-Pop, Drama, Movies and even a place where you can brag about hitting your goals.

Another great (free) resource is the 90 Day Korean Youtube channel.

With new, attention-grabbing posts every day focused on one word or phrase, it’s a quick and easy way to learn some new vocabulary as you scroll through your news feed.

Our Experience Using 90 Day Korean

We enrolled one of our friends to this course, who was a complete Korean beginner.

To their credit, they stuck with the entire course for the whole 90 days and put in the practice.

So did they manage to hold a 3-minute conversation?

Absolutely, and much quicker than 90 days!  We were honestly amazed how much progress was made in such a short amount of time.

Here’s what he said about the course:

I hate studying, and I was always bad at Spanish in school. The words just wouldn’t go in, and I never had the confidence to practice what I had learned outside of the classroom. 90 Day Korean really does work. Not only did it help me get to grips with the basics, but it gave me the confidence to start using Korean to communicate. The personal coach was such a great feature, and I probably wouldn’t have kept up with it, if it wasn’t for her weekly check-ins keeping me accountable. I’m going to continue now into module 2 - the sky is the limit!

Final Verdict

In our opinion, 90 Day Korean is one of the best courses, if not the best course on the market for learning Korean.

If you decide to enrol in the course, the most important thing is to be consistent – practice does indeed make perfect.

Small steps towards a big goal really start to snowball after a while (just ask Will), and before long you’ll be having that 3-minute conversation with ease!
