How it works
Open the semester
Every subject from Semester 1 to 6, in one place.
Pick subject & language
Notes, paper solutions, diagrams — in English or Gujarati.
Read online
Every PDF opens right in your browser — even on mobile.
Why is it all free?
DiplomaOne stays free because of the small, relevant ads shown on the site. Students never pay anything — the ads cover hosting and preparation costs.
What's next
Chemical and Mechanical are live today. Civil, Electrical, Computer and IT branches are being prepared and will be added soon.
