I gave my boards this year from my school south point,kolkata.I got 78.4% .My subject combination was Physics Chemistry Maths Biology and English.I passed in all the subjects.But I want to better my board marks for JEE.For that should I have to give the CBSE improvement exam or the CBSE private exam?? Please help!
And another thing how is the cbse improvement exam marksheet like? Is it a new one? Will i have problems in the future if companies or universities see two different marksheets??
