If you have a keen interest in biotechnology, then B.Tech in Biotechnology is an excellent field. But if you aren’t interested in the branch it will be better to go for other branches. I have friends from both institutes. Here are some of the facts about the Biotech course at both institutes based on the interactions I had with them. 

Comparison:

• Biotech from UIET Chandigarh is decent, but the placement opportunities are limited. But if you have a good academic record then you can go for higher studies at Panjab University which has a good industry interface with Sun Pharma. 
• Panjab University holds a better international reputation than Thapar University. It will help you sail through the admission process in a leading foreign institute for further education in biotech.
• The crowd in UIET Chandigarh is better than Thapar University. The reason is, UIET requires to require a less JEE Mains cut-off rank as compared to Thapar.
• Thapar is a private university. So, it has the edge over the placements compared to UIET Chandigarh. Being a private institution it charges a massive fee as compared to UIET Chandigarh.
• Thapar has a tie-up Trinity College, Dublin, so you get an opportunity to do (2+2), i.e., two years at Thapar and two years at Trinity. This program can hike the fee up to INR 40-45 Lakhs.

Before joining, it will be better to have a conversation with the students on campus to have a wholesome knowledge about the institutes.
