I have passed my 12th class in 2017but I have give improvement exam in 2018 And I failed in it. What should I do?
Improvemnt exams can be given in succeding year only.
Secondly candidates cannot appear for improvement exam if he has failed again.
So you can onky negiven grace marks if possible.
Else you need to apply to private engineering colleges via management quota where you can get admission easily based on entrance exam score of that colkege.
