I have a few friends from VTU and according to them, there are three ways to get this.
By Hand at VTU Belagavi: Go to the Examination Section of VTU Belagavi. Fill out the required paperwork and pay the fee by 12:30 p.m. to receive your documents by 4:30 p.m.
By Post: Go to VTU's website and download the application form, fill it and make online fee payment. Mail the application, fee payment acknowledgment, along with attested documents by post to VTU's Registrar (Evaluation). Documents will be mailed to the address you provided in your application. This can take anything from 7 to 14 days.
Manually at VTU Regional Center, Bengaluru: VTU Regional Center, Bengaluru accepts applications for selected documents. Application forms and fee payments are normally made at nearby Cyber Centers, but instead of sending them to VTU Belagavi by post, you can follow step 2 above and hand in the application at VTU Regional Center. After roughly 8–10 days, you must personally pick up the documents at VTU Regional Center.
Here are some of the things that you should keep in mind.
Hope this answers your doubts.
