SENIORS PLEASE HELP!

This is my first attempt. I am scoring 180-220 range in gts on different platforms. I have revised almost 3-4 times and now in this last week I am not able to solve many questions! I have solved questions almost everyday for the last 6 months but now reading notes is taking a lot of time! Should I keep reading notes or should I solve more questions? I am not able to take out time for questions because I think i should go through my notes again! What should I do? Any advice appreciated!
