Hii,

Yes, candidates can pursue an MCA if they have completed intermediate and graduate coursework in biology. Master of Computer Applications, or MCA for short, is a program that focuses on software and computer science. It is not the same as computer engineering, which is a distinct field with its own M.Tech.

As long as you have finished your graduation, having a background in biology is not an issue for MCA. Although MCA is not the same as computer engineering, you can still pursue it.
