GRE Study advice

I am doing the one-month roadmap & have completed it till the first diagnostic test. I haven’t used my first GRE test yet.
I was wondering if I should learn all strategies for quant & verbal and then give the diagnostic test or if I should directly give it because I don’t want to waste it.

Diagnostic Test is there : to identify what you already know and thus, finding areas in which you can improve. Saving the PowerPrep1 just waste more of time as you don’t pinpoint your mistakes and rather take a broad approach to tackle GRE. It doesn’t matter how much u score in ur diagnostic.

Thanks I will give my diagnostic test
