Expected Study Timeline

I just started studying for my second attempted for the GRE. I got a 312 157Q/155V a month and a half ago. Currently working through the GregMat overwhelmed plan for quant and 1 month plan for verbal. My goal is a 322.

After working through the plans and looking at the strategies, what series do you guys recommend from GregMat to really hone in efficiency?

I worked through TTP but found I wasn’t getting better over time and the course was just too bulky. Not in a specific time crunch but would like to take a ln attempt in the next 3 months and finish the exam overall by the end of this year.

Thanks I’m advance!
