Hello,

I'm sorry to hear about your situation. In the CBSE system, students who have a compartment in a subject usually have to clear it in a subsequent compartment exam. Generally, if you don't pass the compartment exam, you might have to wait until the next academic year to retake it, but the exact rules can vary slightly.

Regarding admission to B.Tech CSE programs, most engineering colleges have specific eligibility criteria, which typically include passing all subjects in the 12th grade with a minimum percentage. With an overall percentage of 49% and two compartment exams in Chemistry, you might face challenges with admissions, as many institutions require at least 50% or more in your 12th-grade exams.

However, some private universities and lesser-known institutions might have different criteria and might be more flexible. It would be a good idea to research specific colleges and their admission requirements or talk directly to their admissions offices to get accurate information.

Hope it helps !
