I was on my final try for my OSCE exam after two previous failures, but thanks to Mark and his amazing teachings, history did not repeat itself a third time. I passed my OSCE because of Mark. I signed up for his one on one four day OSCE prep course and we went through everything, every room, every technique, every stretch and exercise, with unbelievable detail. He even fixed at least half of the assessments I'd been incorrectly taught in school (DO NOT GET RATTRAY FOR ASSESSMENTS!!!). He went over each one until I got it down. He is so patient and supportive and always ended each success with a fist bump.
Mark's knowledge is astounding. He makes up stems to practice on the spot. He'll write you quick lines if you're having trouble getting out what you want to say. He explains what the markers are looking for. He is worth every penny. Seriously.
