Hello Candidate

I understood your concern however joining in inter again by taking mathematics is waste of two year bi.p.c course you done. There are alternatives if you want to become engineer in compture science I would suggest you to take Bsc Computer Science and MCA which are equivalent to BTECH CSE IF you have computer science in intermediate

OR you can do a diploma in CST and after you can go for BTECH IN CSE .

There are other engineering courses available for biology students such as FOOD TECHNOLOGY or BTECH BIOTECHNOLOGY

Hope this information helps you.

GOOD LUCK!!
