Hello,



BSc-BEd programme is of 4 year, and generally done after passing 10+2. Eligibility criteria for DEd too remain the same, now coming to your question,  since you'll be taking admission 2 yrs after 12th (I assume you're pursuing DEd), just make sure to enroll yourself in a college so that you don't face any hassle regarding admission and it goes smoothly as rules varies some prefer pass-out of recent years only, and some not. Usually, the traditional path is going for BSc-BEd integrated program, since BEd allows you to teach higher classes compared to DEd.



If you have any more query, feel free to ask in the comment section.



Hope, this helps.



Thank you!
