You say it like it's obvious haha, it seems completely irrational to me and totally disregards the feelings of those taking the exam. Why can't the scratchpad work like Microsoft paint? Diagrams are a key technique used by those in previous years, yet we are not allowed to use them and then they have the audacity to claim that this is in the interest of parity? It is totally unfair to say to candidates that they just have to use their heads. This is obviously an exam that they want to force online, when it categorically shouldn't be, because of the amount of money they earn from it. The mere reason that they have to introduce so many of these stupid measures is emblematic of the fact it should not be online. Waiting lists and the quality of patient care are increasing and decreasing (respectively) rapidly in the NHS, yet they still want prospective med students to go through all of this just to become a doctor? How's about they increase the number of places on med courses and get rid of this time trial bogus exam we call the UCAT.
