Best free resources for ICAS prep — what's actually worth your time

Compiling a list of what's actually useful for ICAS prep after going through a lot of material that wasn't. Wanted to share what worked for me and hopefully save others some time.

For what is ica specifically, the free resources are surprisingly good. The icas has questions that closely match real exam difficulty — not dumbed-down versions that give you false confidence. For the conceptual background, icas practice test is one of the better free reads available.

What I'd skip: most YouTube "pass in one week" content. The explanations are surface-level and don't prepare you for the applied questions on the actual ICAS exam. Flashcards alone also aren't enough for this one.

What actually worked: timed practice sets with immediate review of wrong answers, reading the official reference material for any concept that came up more than twice, and finding one study partner for accountability.
