Do you think they could have changed it?
DS has just found this : www.medentry.edu.au/ucat/entry/ucat-calculator-how-do-the-ucat-practice-exams-differ-from-the-live-ucat
Which says: The calculator in the live UCAT (i.e the calculator in the testing centre for the actual UCAT) has several differences to the calculator available on the official UCAT practice exams. These changes range from cosmetic (e.g. colour, style) to functional differences.
MedEntry’s Simulated UCAT Exam Platform is the most accurate representation of the live UCAT calculator. You may therefore notice some differences between MedEntry’s UCAT calculator (and the live UCAT calculator) compared to the official UCAT practice exams.
Difference 1: Backspace and Escape buttons
In the live UCAT, the backspace and escape buttons behave differently to the official UCAT practice exam calculator:
Backspace: clears the UCAT calculator (in the same manner as pressing the ON/C button). This button does not do anything in the official UCAT practice exam calculator.
Escape: does nothing in the live UCAT (however, it clears the calculator in the official UCAT practice exam platform).
MedEntry’s UCAT Platform replicates the behaviour of the calculator in the live UCAT.
Difference 2: Clearing memory
In MedEntry’s UCAT Exam Platform calculator, like the live UCAT, memory can be cleared by pressing the MRC button twice. This is in addition to pressing M- followed by MRC:
This suggests that the live UCAT is different from the practice, and more like Medify.
