Need Retake suggestions!

I appeared for my GRE yesterday. My score was V: 141 and Q: 150. I have memorised 75% of the Vocab Mountain. The problem I faced during GRE:

  1. When reading the question, I didn’t understand most of the questions and hence couldn’t identify the support/contrast in the passage. Also in SE, most of the words were unknown to me. I found strong reading problem the whole exam.

  2. In Quant, I figured out that I forgot some of the basic things. I feel like it’s a foundation problem to start.

I was wondering if anyone who got like 160+ on both can provide me with some tips regarding how can I improve my score. Thanks
