Both are almost same but as the name suggests the extra efforts put in to learn two things.. If you're planning to do masters from abroad then CSE + Bioinformatics is a great choice for you. Molecular Biology, Geonomics, Photonomics, etc are studied while doing Masters. Bioinformatics btech will have in-depth knowledge in all 4 years.
