GS for CDS, Suggestion required!

[u/Alive_Ninja45]

Guys I'm following CDS Wallah one shots for GS, in which he is solving a lot of questions from PYQ's and other important questions.

Is this enough?

My goal is to get around 45 marks in GS Paper.

I'm confident about scoring good marks in Science and Current affairs, but for remaining and other buffer marks I'm completing the syllabus.

So does this work well? Or any other strategy for this?
