Self-learning is worth. But what if you don't have time and effort for your interview preparation? That is where interview preparation tools like, AlgoExpert, Leetcode etc. come into the picture.

It's not usual to lack a proper preparation structure when you are on own. Yes, looking at a predefined sequence of actions can hold your hand and guide you to an offer letter.

Nevertheless, sitting in an interview chair with confidence is a first achievement one should reach before cracking the interview.

In this educative review, we will evaluate the real potential of their courses and learning paths. (including their famous recipe - "Grokking the System Design Interview Course")

Why should you seek Interview Preparation Tools?

One can have many reasons for seeking help from an interview prep tool:

  • • Lethargic to refer fatty books and unsorted online resources
  • • Unable to look at a subject from different angles
  • • Lack of proper strategy and guidance
  • • Unable to decide which free resource is reliable
  • • Short of time for your next technical interview
You may have your own reasons. So, spending dollars on quality courses is worth it as it will be rewarding 1000's once you crack a job.

Before going into this in-depth educative io review, you have to know on what basis I'm going to evaluate Educative. Please be noted that my analysis is based on solid research and a decent understanding of the discipline.

In any quality interview preparation tool, factors we might look at are:

  • • Coverage of topics
  • • Quality of content
  • • Value for money
  • • Knowledge of Author
  • • Support on the fly
I will portray all of the above factors from Educative io perspective. You can evaluate if the Educative or system design course suit your preparation.

The in-browser practice environment is impressive, no hectic setup required. Educative says, "Learn 2x coding in half the time". This shows that the curriculum is more focused on speed. 

After course completion, especially grokking series, one may say - "when did I learn this much?". It was such a quality resource that got hyped very quickly, being started in 2015. The course has deep insights into design patterns including core components like sharding, CAP theorem, Web proxy, No SQL.

What does Educative offer:

educative io free courses list and the features

Educative io offers more than 300 courses, everything is interactive and text-based. The course catalog carry two main intentions:

  1. To help you crack a Technical interview
  2. To enhance your Skill set
Out of 300 courses, there is one gem that has generated more than $1 million in sales and made Educative stand out from the crowd. Yes, it is, "Grokking the System Design Interview" (More on this in later section)

In the midst of AlgoExpert and Leetcode who offer video solutions, Educative has managed to mark higher ratings and customer satisfaction with its text-based content.

Note: Free courses doesn't come with free certificate. However, you can buy and download the certificate. If you are solely looking for free certifications, find my list of 18000+ free certifications.

Free Trail at Educative io:

Rather than going for free courses, I suggest you go for a free trial of 7 days. Educative asks your card details required for the free trail. If you don't like their courses, make sure to cancel it, else you will charged automatically. 

Learning Paths at Educative:

Set of topics is a course. Set of modules is a learning path. 

The idea behind this section is to make you understand, "What to Learn?" before "How to Learn?".
This was new addition to user dashboard by Educative. I found this extremely helpful as it specifically curated me to achieve learning goal. The idea is to give you an universal and learnable topic timeline to make you expertise in a matter of subject.

Educative Dashboard Features:

create courses at educative io

Edpresso Community:

Edpresso is like an internal blog in Educative. You can write articles and get featured in their website. You can post and answer topic-wise questions in the community timeline. Top contributors, shot-requests, saving screenshots are key features in community. There will no one-to-one private communication with the peers.

Slack Community:

This was a recent add on. 

You'll not hear much noise. Of course, Educative has nothing to with this. It's ultimately on learners interest to collaborate and discuss with peers.

No Setup Code Playground:

It is not an unknown issue that most online learning platforms require some sort of setup in order interact with the workspace.

That's not the case with Educative. From basic code compilation to kubernetes, everything runs in-browser with no setup.

Create your own course:

yes, you heard it right. At Educative, you are not limited to learn but also teach and earn. (as shown in previous screenshot)

You can create two types of courses.

  • • Complete course
  • • Mini course

Pro Tip:
If you are expertise on any subject, spend time in monetizing your knowledge in course market places like Teachable or Educative.  I don't recommend Udemy for its less pay outs and high competition. That being said, prefer Educative for learning and Teachable for selling courses. Teachable offers great commission rates and has quality customer potential.

Cost of Educative io:

educative io yearly subscription offer priced its Annual plan at $13.99 per month which means you will be billed for $168 on taking a subscription for 12 months. But if you want Educative access for only one month, they charge $49.

By referring a friend, you will get 10% off on the subscription. There is not limit or expire date for referral credits. This way, you can save some bucks using your network.

I feel their monthly charge is overpriced because you will get 6 month subscription for $49 at AlgoExpert. (Of course, AlgoExpert offers only one course where Educative provide 250+)

However, I suggest go for a free trail of 7 days. Get most out of that! If you really like it then go ahead and continue with annual subscription.

Just so you know: charges automatically once free trail completes. Make sure to cancel before 7 days if you don't like their courses.

Possible Negatives of Educative:

If you see my other reviews, this section is something I really focus specially on. That being said, Educative didn't gave me luxury to write negatives as it is good in its way.

Still, this may not be a one stop shop, but a worth stopping halt.  

What they promised is what they delivered.

Educative vs AlgoExpert

If you are not a fan of text-based interactive learning, educative can be an off for you. AlgoExpert is great for isolated visual learning as you can get video solutions for more than 160+ questions in 9 languages. 

Again, at AlgoExpert, system design is a separate course that costs additional $47. You can learn more about AlgoExpert here

Educative vs Leetcode

Leetcode is known for high question volume and diverse topic coverage. Recently they have added video solutions which made AlgoExpert reduce their pricing. 

However, if you have no luxury of time, prefer Educative.
