Grammar is tuff bro

I’m decent at speaking (learnt mostly through movies) and I’m facing difficulty to sail through the mocks?

I’ve tried these rules of grammar videos on youtube and all but no use guys, I’m unable to understand these adjectives, pronouns ka lafda

The TCS pattern ques are quiet easy, i used to feel them and get the answer but ediquity ke ques are quiet tough

If anyone is facing the same difficulty, what are you doing?
And if anyone came over this, what did you do?
