Hi, I did my test last week and got an interview today
There's honestly no real way of prepping apart from maybe refreshing your existing knowledge on roles of a pharmacist, gphc standards etc as it may help you with some of the questions
There are 5 maths questions, they are very simple calculations, not particularly pharmacy based but addition and conversion of units type things
There are 6 situational judgement questions where you will rank responses from the most to least appropriate
The essay is an ethics based question so you won't really need to do any research unless it's stats to support your argument
Best of luck 😊
