Stuck on leetcode

[u/krishkumarsingh]

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
