VAI Diagnostic Exam — What to Expect

Before enrolling in the Veritas Aescula OSSD program, all applicants complete a VAI Diagnostic Test. This is not a pass/fail examination — it is a placement and scholarship assessment that helps us understand your current academic level, identify your areas of strength, and tailor your learning pathway for medical university success.

🎓 Scholarships are awarded based on your Diagnostic Test performance combined with your previous academic record. Strong performers receive merit-based reductions on tuition and additional program fees.

Frequently Asked Questions

Everything you need to know about the diagnostic exam and application process.

No. The diagnostic is a placement and scholarship assessment. All applicants who complete it are considered for admission. Your results inform your cohort placement and scholarship award — not whether you are accepted.
You will receive additional support in that area during the program. The diagnostic helps us design a personalised study plan that addresses your specific needs before and during the OSSD courses.
  • 📝 English: 1–2 hours
  • 📐 Mathematics & Physics: approximately 60–90 minutes each
  • 🧪 Chemistry: approximately 60–90 minutes
  • 🧬 Biology (Google Form): approximately 45–60 minutes
Only the tools listed in each exam are permitted. Calculators are allowed for Mathematics, Physics, and Chemistry. Physics also provides a formula sheet. Chemistry provides a periodic table. No tools are permitted for English, and the Biology Google Form is completed without external aids.
Diagnostic tests are offered on a rolling basis tied to intake cohort deadlines. The earliest recommended application deadline for the September–October intake is March of the same year to qualify for early bird scholarship consideration.
Scholarships are merit-based and awarded according to your Diagnostic Test performance combined with your previous academic record. Strong performers across all five subjects receive the highest merit-based reductions on tuition and program fees.
