Yes, you can use a new Gmail ID for registration for JEE Main 2025 during your drop year. There is no restriction on using a new email address for registration.

Using a new email can help you keep your application process organized and separate from the previous year's registration. There is no disadvantage to using a new email address. The NTA (National Testing Agency) that conducts JEE Main focuses on your application details and exam performance, not the email address used for registration.
