Hiya, I used medify last year for 2 months before my ucat and would highly recommend, I found it was harder than the actual ucat, which made it surprisingly easy once I sat the real thing. Keyboard shortcuts are definitely worth learning as they save you so much time, and do as many mocks as you can, it feels like you want to save up the 25 or so they give you but you’ll likely never actually make it through them all. Also don’t try to do more than one mock a day, if you want to do any extra just do targeted questions or mocks of individual sections. Also second on the flagging and skipping this helped with time management so much. For context I got 3330 b2. Best of luck!
