But like I said, I’ve never sat UCAT so I have no idea how the comparison holds.
I saw several cases on MSO of students who "failed" multiple times with UMAT, the year it changed to UCAT they got in - Keeza, Smelly Boy, Lillysace, Maniacfish... to name a few. So my theory is those not-so-good with UMAT do better with UCAT and vice versa, those good with UMAT would be terrible with UCAT.
I would be one of the latter haha.
