i am not able to score more than 75-80 in Cracku and aimcat mocks, what is to be done now, the English is the main reason for poor accuracy

Dont worry about ur percentiles,analyse ur mocks properly.While analysing find out the following and rectify em
1. Excess time spent on questions
2.Careless mistakes made
3.Wrong Question selection
If ur scoring 75-80 in AIMCATS thats pretty good tbh considering that they are like atleast 2-3 times harder than actual cat and competition levels are way higher than actual cat.
