Pursuing Biotech(BSc) now, Want to change to IT domain.. XII subjects-PCB. What should I do??

I'm currently prusuing BSc(Bio-Tech). However, I now wish to change into Information Technology(IT) domain.





I had a combination of PCB subjects in my +2. I heard that you need to have BTech/MCA degree to enter IT field. I don't have such degree.





Hence, please advice how should I grow and what should I do in order to enter in IT field.
