Stuck on leetcode

Stuck on leetcode

I started leetcode with Striver's sheet, but it didn't had dedicated topics like two pointer, sliding window, so I made my own sheet by exploring leetcode and using AI, solved and understood the topics, and moved to binary search

But noticed that I mostly solved easy level questions and very less medium level and almost no hard problems and now I'm having trouble trying to

Striver's sheet doesn't clarify the topics that's why I didn't followed it.
Neetcode was clearer so should I follow that??
Is there any better sources or a way to tackle my situation

Getting stucked at EDA

I did statistics and probability basics, started EDA but most of the time I can't get what to do in it and what can I actually understand from graphs and plots and when and how to implement what.

Tried with built in datasets like iris and tips to build an intuition and did understood a bit but when doing on real dataset I can't get it much.

Also, I tried doing feature engineering but same happened there.

I thought of studying like this:

EDA -> Feature engineering -> Building models -> Understanding how it works -> loss function in depth and error detection and correction

Am I doing it wrong or any better way to it?

I'm searching for partners for data science, we'll learn and share things.
Individual learners but better being more minds to work together.

Using free resources mostly

I thought of creating a very small group of maximum 5 people
And let's share our stats here so that we can add up to our pace of members

My pace:
I've not covered much of data science, I've covered python mostly, numpy, not much pandas and statistics, probability and hypothesis testing
Haven't started ML yet and I'll be revising my previous concepts now so if our conditions match then please add me to your group

In comments obviously maybe there are people who can add up their group themselves
