The faculty and the labs are excellent at Biotechnology Department. Placements are also good. You will find many students in this department who are really very serious and good in studies ie. better than many students of ECE and CSE. 

Most probably the all-department topper in our first semester was from the Biotech department. You may take it if you are interested in this subject. 

In Heritage, placement means getting placed in the IT sector doesn't matter of any branch. Other branches can't be compared with others, as every branch has its own requirements.

All the private universities in India, except maybe 2–3, are trying their level best to establish themselves and Vignan is no exception. If you are considering joining the university then you should know the following. 

• Fees are high so plan well before joining. For a 4-year long B.Tech, the total course fee is around 9 lakhs. 
• Second, the syllabus keeps getting updated each year. This makes covering the syllabus, a bit tricky. 
• The same faculty will set the question paper so I think getting through with good grades won't be an issue.

Finally, you should join biotech only if you wish to study MS abroad. Otherwise, don’t join the institute.
