Medify is good. Be more careful of tutoring companies that sell you a year long course. Seriously unnecessary to listen to that much "theory" for UCAT, it is more about practice and finding techniques that work for you. That's what Medify is best for. That and passmedicine (a great free resource) are the most suitable.
Keep in mind that tutoring companies have an incentive to sell you long courses to justify the cost. I fell victim to that when I was in Year 11.
Best of luck! Happy to answer any further questions
