Hello. Unfortunately if you do not have biology as a subject in your 10+2 then you will not be eligible for NEET or for that matter any other medical exam. With a combination of Physics, Chemistry and Maths you can opt for engineering, bachelor's in Science or go for the research field among many options. You just won't be eligible for the medical stream or any exams associated with it.

Hope this helps. For more queries feel free to comment down below

Hello alam bhai

Agar apne  12 th mein Biology register nai kiya hai to aap NEET Exam nai de sakte hain. Because agar aap guidelines dekhe to usme sabse pehle eligibility criteria ye kehta hai ki appka 2 sal ka continous study hona chaiye Physics, Chemistry and Bio ke sath han uske sath aap kisi bhi subject ko optional rakhe.

Ek aur bat agar PCMB hai tab aap likh sakte hain Exam kyonki usme Maths ek optional ki taraf kam karta hai.

Shukriya.
