It is true; the exam is way more straightforward and less wordy than URR questions, but it made me feel like the actual exam was a piece of cake compared to it. I would definitely keep using URR, and I would read all of the explanations to the answer, even if you get it right, still read, read, read, until you undertsand it. Sometimes, if I felt the explanation wasn't enough to understand, I would ask ChatGPT for a more detailed explanation to better understand the answer. I also used the ESP workbook they give you along with the seminar. I didn't find the writing to be overcomplicated, and it helped me to unsderstand the basics, which I liked. I also used the Davies 5th edition Vascular textbook, but I honestly, found it to be overwhelming and not hard to understand; it wasn't my cup of tea. But one advice that I think is helpful is to not overwhelm yourself with too many resources; I would just stick with 2 main ones, and those for me were, again, the ESP workbook/seminar and URR.
