Hello Aspirant,

I hope you are doing well.

According to the requirements for admission to the BTech programme applicants must have received a minimum proportion of marks in Physics, Chemistry, Biology, and Mathematics in their 10+2 exams. So, yes! You can enrol in the BTech  if you have biology knowledge, but you must take an entrance exam to enrol in any engineering course. The engineering entrance exams now require three subjects, including mathematics, physics, and chemistry. You must therefore pass the entrance mathematics exam because it is required for all engineering programmes.

Hope this was helpful. you have a wonderful day!
