MUIC entrance exam

Hi guys ! Anyone ever taken the MUIC entrance exams ? I’m not worried about the English portion mostly just the maths. I haven’t done maths since high school and it’s not my strongest subject just wondering how hard others found it. I have seen there’s a mathematical foundation program if it all goes really badly but I’d like to not have to do that. I’m looking at doing one of the science programs they have- any idea what percentage I might need to achieve in order to pass? (I haven’t seen any publicized grade boundaries) Thank you :)
