So I scored 98 percentile in first attempt of jee mains the paper didn't go so well but the april attempt was good or as i thought my accuracy dropped further and before the results came out i had bitsat paper on 15th April shift 2 which i wasn't very much serious about bcz i though ki jee toh hai he bitsat ki ab zarurat nhi hai and also I never gave any mock for bitsat in the first place and didn't revise anything the day before (completely opposite to what i normally do) anyways i scored 190 marks in bitsat 1st attempt. I want only top tier clg cse or mnc or data science so should I focus on advacned or bitsat and how should I prepare for the paper?
