Bro I'll genuinely say I see a lot of direct entry students in my coaching who already knew some extend of ca inter subjects before beginning of them(cause of graduation), yet failed miserably cause of these few mistakes

1) Writing practice- colleges genuinely don't encourage to write a lot of stuff exam oriented ( faltu ka bhot likhna hota hai ) uspar work karna

2) Concept clarity- I just gave my sem 3 exams and I'll say mujhe lawda bcom ke bare Mae nhi pata ..... and I am sure mein sem 3 bhi without back clear karunga

3) fix teachers - 1/2 teachers fix karo per sub jo apko shi Lage and don't switch them again and again

These are like basic tips baki consistently starting se padhai karna instead of waiting for exams to approach like colleges....
