Hi, I had a similar dilemma applying this year. I ended up doing the two practice tests online (one with meds for attention difficulty and one without) the result was that I was in both cases under time for the tests, though without meds brought me really close to the threshold. In both cases I scored a 27/42. After doing this I decided not to get extra time. I completed multiple choice with 5 mins to go, but my essay was literally to the wire with like 2 secs to go. I scored a 26. Any other questions feel free to ask!
