Need advice!

A few months back I decided on taking the GRE, but I didn't set a deadline and book the test, because I got intimidated by the very first diagnostic test, which I left incomplete.

I've been studying inconsistently for the last two months. I've studied only quant from the I'm Overwhelmed Plan and memorized 10 groups of vocab. But now I want to take it seriously and get it done without procrastinating or delaying anymore.

I took the quant foundation quizzes today and can conclude that I've solidified my foundations.

I'm confused about how to proceed further. Should I follow the 1-Month or 2-Month plan? I have plenty of free time and want to take the test in 2 months.Also, should I begin right from Day 1 for both quant and verbal, or should I skip ahead to the strategies section for quant since my foundations are solid?

Target scores: (165Q, 155V, 4.0W)
