Quant Mountain (I'm overwhelmed) vs Quant Mountain + Quant Flashcards?

Hello everyone. On Sept 25th I gave the GRE and received an undesirable score. I’m currently working on making my foundation stronger and giving the GRE again. For Quant, I was exploring two options: 1) Doing the Quant Mountain Overwhelmed Plan (Of course, I won’t take 48 days to do them) or simply doing the normal Quant Mountain + flashcards.

Also, I do not know if I need to do both the mountain and the flashcards both or if they have all the same material. Open to all suggestions.

I haven’t booked a slot yet, but I’m thinking to give it around the 25th October.

Seeking your advice.

Thanks in advance!
