In cbse class 12th ...i.have got 374 marks out of 500...am i in top 20 percentile?
top 20 percentile means that you should score more than 80% of the students who took the exam. but for jee main, qualifying marks in board is 75%. As number of students applying for cbse 12th board is more than 10 lakh so is 20 percentile is around 80%
So you are not in 20 percentile
