Hello,
Since you are a diploma holder in mechanical engineering and want to pursue BTech part-time, you can look for universities or institutes that offer lateral entry into the second year of BTech for diploma holders. Check the eligibility criteria, course structure, and mode of study before applying. Part-time BTech programs allow working professionals or diploma holders to continue their education while managing other commitments. Make sure the institute is recognized and provides proper support for part-time students.
Hope this helps you.
