Hello,

The eligibility criteria for B.Tech programs may vary depending on the institution. In many cases, a passing grade in the relevant subjects (such as Physics, Chemistry, and Mathematics) is required for admission to B.Tech programs.

If you have passed in all six subjects, including Biology, but obtained an RT grade in Biology, it's essential to check the specific admission requirements of the B.Tech programs you're interested in. Some institutions may accept a passing grade in Biology, while others may require a certain minimum grade.

Hope this helps,

Thank you
