Would it be the last one?
Math sections are roughly the same difficulty compared to each other. Questions in each section are generally ordered easiest to hardest (grid-ins are also ordered).
@MITer94 Ok! I just did one section, got 19/20 (set the q up right but solved it wrong). So should I expect to miss 1-2 in each section??
Maybe, of course you might miss zero on one section and 3 or 4 on another due to careless mistakes.
