Did coaching institutes misguide us?

Teachers used to advise us that do

12 ques in VARC

6-8 ques in QA

1-1.5 set in DILR

And this would be sufficient for you to achieve a decent percentile !! I'm an average student and I know my potential so I wanted to play safe hence I practiced all my mocks with this strategy and did the same in the exam.

Ghanta kuch nhi hua is se !! Upar se thik se paper attempt nhi kar paayi ye soch kar ki kahi negative na ho jaaye accuracy kharab na ho jaye Bhyi I was thinking ki ab toh safe hu

My dumbassssss missed 3-4 doables due to fucked up practice

Teachers from my so called renowned coaching used to tell us this. Ab kya karu mai iss bizzare result ka ???? I'm so fucking frustrated and scared.

I know... I'm way too dumb to believe them blindly lekin ab kya karu ?? I can't take a drop either
