Can a child who has studied computer science study any medical field? If so, which ones?
Yes you can surely study medicine if you have the required subjects in class 12th to be eligible for the medical entrance exam .
The subjects required to be eligible are Physics, Chemistry and Biology in class 12th failing to have any one of the subjects, you cannot study medicine.
In short if you had PCMB or PCB in class 12th you are eligible and a mere PCM makes you ineligible for the same.
