Failed my ACS exam twice — what finally helped me pass

So I finally passed the ACS General Chemistry exam last week after two failed attempts, and I just want to share what actually worked because I spent months searching for good advice and couldn't find much. My first attempt I scored a 58 (passing is 68 at my school) and I basically just re-read my textbook. Second attempt I jumped to 63 but still missed it. I was ready to give up honestly.

What turned things around was finding a decent ACS practice test that actually mimicked the format — multiple choice, no partial credit, that weird way they phrase answer choices to trip you up. I also grabbed an ACS study guide from my university library and went through every single topic outline they list. Thermodynamics and equilibrium were my weak spots, and I drilled those hard.

Has anyone else noticed the real exam leans heavily on conceptual questions vs. calculation-heavy ones? My third attempt I shifted my prep to focus on "why" over "how" and went from 63 to 74. Curious what worked for others, especially if you're retaking it.

Congrats on passing! Honestly the format is what gets most people. I used the official ACS study guide plus did like 3-4 timed practice sets in the last two weeks before my exam. Timing yourself matters more than people think — I was running out of time on my first try. Also don't skip the organic sections even if your course didn't cover much, there's usually a handful of questions from there.

I'm in the same boat right now, taking it for the third time in two months. Can I ask what ACS practice test resource you used? I've been using random Quizlet sets but they don't feel like the real thing. I feel like the answer choices on the actual exam are specifically designed to catch you if you half-understand something. Any specific tips for equilibrium? That section destroys me every time.

Equilibrium + electrochemistry were brutal for me too. One thing that helped: drawing out every ICE table by hand even for simple problems until it became automatic. Also, exam tips I got from my prof — never leave blanks, there's no penalty for guessing. Changed my approach completely.
