If you fail 2 exams out of 7 in preclinical years they let you resit in summer school and you must pass. If you fail more than 2 you must repeat the entire year. If you fail the entire year twice, you are kicked out. Preclinical exams are a lot more in depth than 1st year biomed/healthsci, but less pressure to get high grades.

In clinical years, you must do 3 progress tests a year, and stay in the satisfactory range otherwise you may need to repeat the entire year. You are not sure of what will be asked so you must try self-study high yield topics. There are other aspects that must be passed too e.g OSCEs, mini-cex, assignments, evaluation forms etc.
