You can't get a fully accredited B.Tech degree completely online in the same way you can get some other degrees. B.Tech (Bachelor of Technology) programs, particularly in India (where the degree is most common), typically require significant hands-on laboratory work and practical experience. While some universities might offer some online components within a B.Tech program, the core curriculum almost always mandates in-person attendance for labs, workshops, and potentially some lectures.
Therefore, while you might find online resources, individual courses, or even some blended learning options within a B.Tech program, a fully online, accredited B.Tech degree is extremely rare, if it even exists at all, from reputable institutions. Any such program should be viewed with extreme caution. Check the accreditation very carefully before enrolling in any program claiming to offer a fully online B.Tech. Accreditation ensures the quality and validity of the degree.
