Hello Aspirant,
You have academically low score in your 12th board examination and to get admission in good engineering college, you need to appear for JEE MAINS examination for which the cut off is high.
The selection criteria in engineering college is based on the aggregate percentage of 12th board exams and your JEE MAINS qualifying percentage. If you have good score in 12th board examination then your aggregate will be good and you will get a seat in government college. Since you have only 35% marks in your 12th boards, you have to study hard for JEE MAINS exam and try to score good marks in that so that your 12th board marks will not cause a problem in your admission.
All the best!
