Hello Abhit,

Admissions to IHMs is done on the basis of your score in NCHMCT JEE 2019. The overall score is indicative of your performance in all 5 subjects: Numerical Ability and Analytical Aptitude, Reasoning and Logical Deduction, General Knowledge and Current Affairs, English Language and Aptitude for Service Sector. The 3 subjects you do good depending on how much weightage they have in the exam will determine your rank. If two out of three of them are English Language and Aptitude for Service Sector, then it will improve your ranking more.

If by subjects, you meant 10+2 subjects, then it does not matter as long as you Pass in Senior Secondary Examination (10+2) or its equivalent with English as a subject of study.

Hope this answers your query, feel free to ask for more info.
