My dad is literally going to ruin my boards and jee

Since July yar mere papa Mera tution laga diye Coaching se Ata hu 4 baje fir 2 ghanta tution aur Weekends me toh teeno pcm+English ka lagta hai English ka 1.5 hour baki pcm ka 2 hours each Mai bola ki self study ka time nahi nikalta toh wo "paise kharch Kar raha hu mai tumhare peeche tution aur coaching laga kar" wala dialogue chipka dete

Ye sab se pehle mere 180-190+ aa rahe the har test me out of 300 but ab performance dip ho rahi hai and now I score between 130-150 and somehow that's my fault as well
