Hi student,

After BCA, the MCA course would be the best but if you have interest in masters in science than M.Sc. would be better than MCA. If you are neutral for both than MCA would be the best for your future as what you have studied in BCA, the advanced version of that would be in MCA.

Feel free to ask doubts in the Comment Section.

I hope this information helps you.

Good Luck!
