OAT scoring & marking scheme
Strategy: OAT has no negative marking. Attempt every question — blank answers cost you potential marks but cannot pull your score down.
Scale: OAT (200-400).
How OAT is conducted
Mode
Standard — practice without proctoring on Wrexa Edge, or enable optional webcam proctoring to simulate test-day conditions.
Test format
Linear / fixed-form — every candidate sees the same number of questions per section.
Backtracking
Allowed — you can revisit and change answers within a section.
Mark for review
Available — flag tough questions and return to them before submitting the section.
Tools available during the OAT exam
Wrexa Edge renders these tools inside the mock test exactly as they appear on the real OAT exam — same shortcuts, same behaviour.
OAT time strategy
With 180 questions in 185 minutes, you have about 62 seconds per question on average. Successful candidates aim for the following pacing on each section:
Natural Sciences (100 Q)
Target ~54 sec/question. If a question takes more than 81 seconds, mark for review and move on.
Reading Comprehension (40 Q)
Target ~75 sec/question. If a question takes more than 113 seconds, mark for review and move on.
Quantitative Reasoning (40 Q)
Target ~68 sec/question. If a question takes more than 102 seconds, mark for review and move on.
Wrexa Edge's analytics show your actual time-per-question after every mock so you can spot which sections you're losing time on.
