Advanced Diploma In Computer Application (ADCA)

By NCTA Team Last Updated: October 31, 2026

ADCA online — with no minimum duration

Most computer diplomas lock you into a batch: fixed classes, fixed exam dates, a fixed year. NCTA's ADCA (Advanced Diploma in Computer Application) works differently. The entire program is 100% online, the study material is yours from day one, and there is no minimum duration. If you can cover the material in 7 days and pass the online exam, we certify you in 7 days. If you'd rather study casually over a year, that works too. Same material, same exam, same certificate, your speed is the only variable.

One honest note: this is a year's worth of learning content. Finishing it in a week means full-time study, and it suits candidates who already know some computers and mainly need the paper. Most candidates realistically take two to three months. Choose the pace that matches your situation.

Mode 100% online — self-study material + online exam

  4. Take the online exam when you feel prepared : from home
  5. Download your certificate on passing : verifiable online by any employer in minutes
