Experience ADAT-Style Questions
The ADAT tests biostatistics and clinical reasoning. Try these questions to see what you'll face.
A clinical study evaluated a fluorescence screening device for OSCC on 1,000 high-risk patients (smokers over 50). Results were compared to histopathological biopsy.
OSCC Screening Device vs. Histopathology
| Disease +Disease Present (OSCC+) | Disease -Disease Absent (OSCC-) | Total | |
|---|---|---|---|
| Test +Test Positive | 45TP | 190FP | 235 |
| Test -Test Negative | 5FN | 760TN | 765 |
| Total | 50 | 950 | 1000 |
A patient in this high-risk population screened positive using the new fluorescence device. What is the probability that this patient actually has Oral Squamous Cell Carcinoma (OSCC)?
Why the ADAT is High-Stakes
For Canadian programs, this isn't just a test—it's 70% of your application
The Problems
Stuck With No One to Ask
You don't understand a concept. No study group. No tutor on call. You re-read the same paragraph hoping it clicks.
The Stakes Are Massive
At McGill, ADAT is 70% of your assessment. At U of T IDAPP, it's mandatory. This IS your application.
Biostatistics Catches Everyone
40 questions on study design, p-values, confidence intervals. Haven't touched biostats since dental school? It shows.
No "Passing" Score
The ADAT is competitive, not pass/fail. A 450 won't cut it for competitive programs. You need to be in the top percentiles—average isn't enough.
