I do not have much idea about the problems you can face in future but still you have an advantage with moving with an work experience and a course which you have already done in that field. You can pursue BCA that would be more helpful for you in future for job opportunities.

As much as I can understand your question, you are going to pursue 12th this year and apart from BCA, you want suggestions to pursue other courses.
Well I myself is a student of MAKAUT and pursuing BSC in Media Science.
There are plenty of courses to apply for, since your background is Biology, you can go for BSC in Physiotherapy, BAMS, BUMS, BHMS, travel and tourism course, media, fashion designing etc.
Plenty of field is open for you, I'd suggest go where you feel you can do it well.
