Am I prepping LC the wrong way?

YOE: 4
TC: 180

Been prepping for interviews past 4 weeks for Meta and Amazon April phone screen and here is my current plan:

Grokking the Coding interview (85% complete with Bitwise XOR topic skipped)

How I studied so far:
I would spend a couple hours per day for 2~3 days per pattern solving the questions and try to fully understand the solutions and also solve the equivalent questions on LC.

And whenever I go to the next topic, I repeat the challenge questions from the previous topic and see if I can solve them right away. If I struggle with any of the challenge questions from the previous pattern, I repeat them every day until I can solve them comfortably alongside studying the new topic.

While I do this, I put the general summary of the solutions for each question's I've solved in google sheets and review them from time to time. So far, it shows I've solved around 100 questions past month.

I'm probably going to finish this course this week so my next plan is to go through EPI and company tagged LC questions and follow the similar approach I did with Grokking.

Am I prepping LC the wrong way? Is there a better way to learn the patterns and stuff?
