PP1 test diagnostic

I am following 2 months plan and gave PP1 for diagnostic. I scored 302(Q-159 and V-143). For now, I am satisfied with my quants as in coming few weeks I will cover the concepts in more detail.
I found the verbal to be okay but face issues in the vocab. I have always face issues with vocab. I am not a reader so reading books is not an option for me. I am practicing remembering mnemonics but its not very useful. Any suggestions?
