Hii Pratham..

For getting admission at uiet Chandigarh I am providing you the eligibility criteria.

The minimum eligibility is-

Required Eligibility Criteria based on Class 12th / Equivalent qualifying examination: 1. Language 2. Physics 3. Mathematics 4. Any one of Chemistry, Biology, Biotechnology or Technical Vocational Subject 5. Any other subject. Only those candidates are eligible who have passed class 12th with at least 45% marks in aggregate (40% for the candidates of reserved categories).

Thus, it is not compulsory to have Biology in class 12th for pursuing biotechnology engineering in UIET Chandigarh.

Even if you are a PCM student are eligible to get admission in this college in biotechnology engineering.

Hope it helps. 

Best of luck for your future.
