Tips:
Read up and practice first. We all failed one of the PE stations. I'm talking below 3/10 here.
Revise how to take history again. ObGyn, Endo... Hypo, hyperthyroidism.
READ question properly. You might not need personal details.
Visit MMS to look at pictures of patients with conditions. Self-standing questions are like OSPE.
really... Read up again. Seriously.
but then again, this is just a Mock Exam.
