Hey mate, can’t comment on the quality of Konvexity mock exams, however just to your last point - don’t feel too down just now and keep at it. Look through your results and work out what areas need further attention, don’t feel bad about going back to the text to the relevant sections or even using the text to search for details while you sit your next mock… Just keep grinding it out, you can do it. Best of luck
On average, I am generally scoring a little bit higher on Schweser and CFAI compared to Konvexity. But I still find them to use very testable material, and I would definitely recommend that you do them given that you have the time. I’ve done two of the three Konvexity mocks so far.
I personally liked Konvexity mocks. They were very similar to the real exam. I like Kaplan’s mocks as well. I scored very similar in Kaplan, Konvexity and CFAI’s official mocks.
To be honest, the exam is actually slightly easier than all three.
