Q:   If I opt to participate in second round of NEET UG counseling, will my allotted seat of first round be cancelled?
A: 

In case candidates are not allotted any seat in the second round of the NEET UG counselling, the earlier allotted seat in Round 1 will be retained.

Therefore, candidates are advised to fill in only higher choices or any other choice which they prefer over the earlier allotted seat, for second round.

No, you do not need NEET for a B.Sc in Microbiology. For most B.Sc courses, colleges use your Plus Two marks to make the rank list. The University of Kerala says no entrance exam is needed for most of the Microbiology programmes. You apply online through the university's CAP portal.

No national exam like NEET is not needed for B.Sc Forensic Science. For a related field, criminology and forensic law colleges in Tamil Nadu, admission is mostly based on merit in the qualifying exam. Some deemed universities may hold their own entrance test or interview.

Yes, in most colleges. NCAHP said NEET UG will not be mandatory for BPT and BOT in the 2026-27 session. Many colleges admit through Class 12 PCB marks or their own tests. Top government colleges like KGMU still use NEET. Check each college's notice. Keep your PCB marksheet ready.
