Hello aspirant,
Unfortunately, securing a seat in CBIT for Biotechnology with a TGECET rank of 48000 is highly unlikely, because of the following reasons:

High Competition: CBIT is a popular engineering college, and Biotechnology is a sought-after branch.

Cut-off Ranks: The cut-off ranks for Biotechnology at CBIT are usually much lower than 48000.

Seat Availability: The number of seats available for Biotechnology is limited.

While getting into CBIT might be challenging, there are other options to consider:

1. Explore Other Colleges: There are many other good engineering colleges in Telangana and Andhra Pradesh that offer Biotechnology programs.
2. Consider Different Branches: If Biotechnology is a strong preference, you can explore other colleges that might have lower cut-offs for this branch. Alternatively, your son could consider other engineering branches with a better chance of admission at CBIT.
3. Improvement Options: If your son is determined to get into CBIT Biotechnology, he could consider:
   • Preparing for entrance exams like JEE Main or BITSAT to explore other options.
   • Improving his academic performance in the future for potential management quotas or other admission rounds.

It's essential to have a backup plan and explore various options.

I hope this information helps.
