That’s not how it was when I applied pcoltas. 1a was the simple facts and figures entry part; 1b was a 4 part written question/response (including why you believe you are suited to your chosen career etc); Stage 2 involved aptitudes and maths; Stage 3 consisted group exercises and an interview and stage 4 was a final sim check. Correct me if that’s changed, but I certainly wasn’t aware that it had.
