Hi,
Actually securing 75% in engineering is not a tough task you can easily get ,just be attentive in class ,clarify all your doubt .Try to be up to date in all your subject.Belive me you will get more then 75% if you do so .

Hi aspirant

Thanks for asking your query,for securing 75 percent in engineering is not a big deal,You have to be consistent and hard working.Generally students of engineering don't attend their classes regularly and this effect there performance in semester exams.To score high and get good percentile is the matter of proper time management and consistency.You should also stick to your syllabus and should not do chapters beyond it because time management is very important during the semester examination.
Hope this will help you
