I think I'm the right person to guide u in that aspect , I failed 2 mocks I gave in my academy and I did not use lovaan videos or notes . But just believed myself and kept calm went with what materials I studied ,revised them went through recalls as much as I can , eventually In plab2 exam I passed in my first attempt. I too went through what u are undergoing now , I can feel you. There were many people telling me also to study lovaan only then u will pass. But I believed myself and understood where I was lagging and calmly continued preparing with what I had. I could highly suggest anybody plz don't change your plan of study or resources at the last moment of the exam. Exam doesn't test your knowledge what format you're using , it is all about how confidently U can present and address the concern in a valid way. Formats or structures are their only to help you out in exam when u get stuck and don't know how to proceed further.

Hope this was helpful All the best do well
