Need help in Reading comprehension section and verbal section too

So I am preparing for almost 2 months now and have my GRE on either 13th Nov or 21st Nov(as i haven’t booked it yet)
ETS Test untimed- Quants 34/40 ; Verbal 16/40 correct
I think i can score 165+ on quants by grinding more.
But verbal section is still a hit an miss for me, I given this test and got all SE questions correct but on Reading comprehension got only 4 correct. I practiced a lot but still doing silly mistakes, i know that this is answer but due to always being skeptical i just change the answer option and end up getting it incorrect and realizing that the initial answer i thought was completely correct.

BigBook is gold for practicing RCs

Yea I’ve found the best way to get better at RCs is to just do a ton of them.
