dear utkarsh
you cannot attempt jee advanced in next attempt due to cappling limit of 2 times max .
so, in next year you can appear mains only , its acc to new regulation by HRD ministry .
so, please prepare best and give best this year jee advanced exam , else go with bitsat , ipu cet , and viteee , there are more college as well , like thapar , bit mesra etc .
but taking drop again a year will be a huge loss as u take 1 year drop already , so, again by doing this you will nervous and will get frustrated .
so, better join any engg college this year only .
regards
kindly approve
