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

Congrats on passing! Can I ask — how many questions did the actual exam have compared to what the practice tests simulate? I've seen different numbers online and want to calibrate my timing during practice.

For the people asking about study timelines: I studied 89 minutes per day for 12 weeks working full time. It's absolutely doable without burning out. The key is consistency — missing days hurts more than extending your timeline.

The part about reviewing wrong answers thoroughly is so underrated. Most people just move on after getting something wrong. Going back to understand the concept is what actually builds retention for the COA.

Late to this thread but wanted to add — the coa section trips up more people than any other part. If you're scoring below 75% there in practice, treat it as your only focus for at least a week before moving on. Breadth at the expense of depth in that area is a common mistake.

Honestly I almost gave up on COA prep. I'd been burned by so much junk material that when people kept recommending free stuff I just rolled my eyes. Figured if it's free it's probably useless. I was wrong. I kept going mostly out of stubbornness and the coa practice test pdf is what actually turned things around for me. The questions are close to the real thing. Not vague, not padded, just solid practice.

So if you're sitting there thinking none of this is worth your time, I get it. I felt the same way. But stick with it. I ran through that pdf a few times, started recognizing the patterns, and walked into the exam way calmer than I expected. Passed first try. Don't write off the free stuff like I almost did.

One thing that really changed how I studied was stopping myself from just circling the right answer and moving on. I'd go back and figure out exactly why each wrong option was wrong, not just that it was wrong. Sounds tedious but it cuts down on the "I know I've seen this before" panic on test day because you actually understand the logic, not just the answer.

It's a slower way to study but honestly you end up needing way fewer hours overall. Once you can explain why a distractor is wrong, the real question becomes easy. Didn't fully get that until I was already halfway through my prep and kind of wish someone had told me earlier.

Quick update for anyone following this thread -- I just hit 78% on my last practice run, which felt pretty good considering I was sitting at 62% two weeks ago. The sterile processing questions were killing me at first but they're clicking now. Still a little shaky on some of the infection control stuff so I'm hammering that this week.

Planning to sit the real thing on the 28th, which I know isn't a ton of runway but I feel like I've got enough momentum going. Honestly didn't expect to move that fast but consistent daily practice really does work. You don't need to spend hours at a time, even 30-45 minutes a day adds up faster than you'd think.
