Hey Gobinda! With 49.5% in Class 12 and being from the OBC category, you still have a chance for B.Tech (including Computer Science). Most colleges ask for around 50–60% for General, but for OBC there is usually some relaxation (around 45–50%). Since you are in that range, you can definitely try.

Just make sure you had PCM (Physics, Chemistry, Math) in Class 12, because that’s compulsory for B.Tech. Some universities admit on board marks, while others through entrance exams like JEE Main or state-level tests. Private universities are also an option if you don’t want to depend fully on entrance exams.

So yes, you are eligible, but it will depend on the college/university you apply to. Best option is to check their specific eligibility on the official website before applying.
