Hi Arya das,

This is Nikhil Reddy

If it is clear that you want to crack jee then you have to go through PCM which helps in getting good score and makes it easy to fetch marks in mathematics. 

Else if you are very much interested in biology and you want to pursue degree in computer science then you can take MBiPC but it gives you less time comparatively to each subject in preparation and makes you difficult in preparation. 

But by taking MBiPC you can crack KVPY(there  you have to choose 3 subjects in the paper out of 4, you can go through all 4 and can attempt best 3) and get scholarship and admission In IISC ,IISER'S , and other top colleges. 

So if you are sure to get in CSE then I prefer you to go with PCM. 

I hope  your doubt had been cleared for any queries regarding this and jee  , other engineering and graduartion entrances please follow me and ask..  

Thank you. Have a good day.
