Hello,
Since you completed your Diploma in ECE in 2007 in Andhra Pradesh, you are already considered a diploma holder. If you want to continue your education now, you have options like:
Join B.Tech through lateral entry (you can join directly in 2nd year).
Do certification courses in electronics or related fields.
Apply for government or private jobs that accept diploma holders.
If you meant that you did not complete your diploma and want to finish it now, you can contact your polytechnic college or the SBTET (State Board of Technical Education and Training), AP to check rejoining or reappearing options. They may guide you on how to complete the course after a long gap.
Hope it helps !
