Hello,

Unfortunately, Hindi cannot be counted as a fifth subject for JEE Mains eligibility. Here's why:

1. Required Subjects : For JEE Mains, candidates need to have Physics, Chemistry, and Mathematics as core subjects.
2. Additional Subject : One additional subject can be considered, but it generally refers to subjects like English, Computer Science, or a related elective.
3. Physical Education : Though it is a valid subject in school, it is generally not accepted as the fifth subject for JEE eligibility.
4. English Consideration : English is typically considered part of the core subjects in many boards.

Hope it helps !
