Hi there,
If you are a standard applicant, they will be looking at your OP. According to their website (
Medical Program^ entry requirements), data from the most recent intake indicates "that to be considered competitive... an applicant would need to achieve a minimum academic rank of OP 1 - 2". It does not, however, explicitly state that higher OPs are not considered; it just implies that higher OPs are not competitive. Perhaps contact them directly to see if it is possible to receive an interview offer with an OP 3. Good luck with everything!
