Hello dear student,
Yes you can apply for neet as well if you are preparing for jee mains but only if you have biology too with physics, chemistry and mathematics . As pcm are the subjects you would be studying for jee mains. But if you don't have biology as a subject then I am really sorry but you cannot apply for neet.  I hope this was helpful
Best wishes

Dear Dhivya, hope you know that JEE Mains and NEET are 2 different examinations for 2 different professional courses. NEET is the entrance examination for admission to Medical, Dental, Ayush and Veterinary courses across India. JEE is the entrance examination for admission to Engineering courses across India. Their reach is different and their prospects are different. Having said that, we shall help you with the eligibility criteria of JEE Main. If you fulfil that criteria, you can fill in the application form at: https://testservices.nic.in/examsys/root/Home.aspx?enc=Ei4cajBkK1gZSfgr53ImFQTbjVzuZ1mQajFt6EnKeZEk28J/HZOEuCngppd8/JG7
