@gapyearapplicant : I mean the ACT or SAT is multiple choice so doesn’t measure the ability to take the types of exams a challenging instructor would give. Imagine your organic professor giving a test with items at the level of this International Chemistry Olympiad Exam, but requiring a higher level of knowledge and creativity (so you get the complex structures and scenarios, but then they ask you to basically “propose a model for this phenomenon” or not just to draw a structure but “propose a mechanism for this transformation” and it, like this IChO exam is likely something you haven’t learned and they just pulled from the literature or their behinds : https://www.iuventa.sk/files/documents/5_icho/past%20competition%20tasks/volume3-icho41-45.pdf
That is what you get when you take either of the two most revered instructors for it. It is nothing like an ACT. It would be like if each midterm were an ACT or something and contained the analogs of its most difficult items for a substantial chunk of the test. Scenarios and questions may be no where near as predictable as an ACT or SAT. You have to literally just sit there and try to interpret what is happening and then kind fudge things to work.
