Hello. Im also attempting OCS this November. i was exempted from F1 & passed E1 & P1. Apparently case study is mainly technical, so you’ll have to apply your knowledge of F1, P1 & E1. It will be important to go through the notes to try and understand the theory and the models, but I think attempting the 0T’s will not be necessary because the structure of the exams is totally different.
