Yes dear its possible to pursue BTech with computer science with 68% in class 12th , some colleges may have higher percentage requirements and many offers admissions based on 12th marks

You can explore private engineering colleges or you can try for those colleges that have less admission criteria based on your category.

1. Minimum eligibility:- Mostly BTech program requires minimum 50% marks in class 12th with Physics, Chemistry and Mathematics as a core subject.

2.Category relaxations:- Students from reserved category might get relaxations and have lower marks requirements.

3.College Criteria:- Some colleges may have higher marks requirement .You should go for private engineering colleges as they will be more flexible in admission requirements.
