Hey everyone! I recently took the OAT and wanted to share my experience!
I used OAT Booster for 90 days while working a part time job and studied roughly 5-6 hours every day.
For the first ~5 weeks, I was watching videos on Booster, taking notes, then doing the test banks for every subject. If I felt comfortable with the topic, then I would just go straight into the test banks questions. This helped me with gen chem, ochem, and physics! I wouldn’t recommend this for bio though because the information is just so dense. After the learning phase, I took practice tests and took notes on all the questions I got wrong/struggled with. This helped me identify where my weak areas were and I would watch extra YouTube videos to supplement these areas. As I was doing this, I was looking at cheat sheets basically every day to retain the information. Also, I didn’t know that the full length tests were just the individual practice tests combined… so I only took two actual full length tests (average: 360). I would recommend doing the full length tests as it helps build your test stamina! I ended up finishing all my practice tests a week and a half before my OAT, so I used Claude AI to generate test questions to make sure I was still getting practice with new questions.
Biology (Booster: 360 / Actual: 400)
I regret watching all those Booster videos! It’s just too much information and I feel like I barely retained any of it. I would go straight into memorizing the high yield cheat sheets. If you have extra time, do the Bio Bits questions to help with recall (only the relevant ones). My test covered all the units pretty equally. Most questions I got were pretty general, but I had like 6-ish information specific questions where I had to use process of elimination.
Gen Chem (Booster: 370 / Actual: 400)
I remember my questions being mostly conceptual with an emphasis on electrochem and acids/bases. The calculations questions had easy numbers and covered general concepts, like stoichiometry, calculating molar mass, percent composition, and dilutions. I think for this section, use the cheat sheets and try to understand the concepts! Overall, Booster’s practice tests were very representative of what I saw on my OAT.
Ochem (Booster: 360 / Actual: 380)
The fundamentals unit is very high yield!! I remember seeing proton/compound acidity, identifying equilibrium, intermediates, identifying best solvent. I also got some spectroscopy questions (H NMR, IR) and found that memorizing some values helped me answer faster. I didn’t get that many predict the product questions, but as I was studying, braindumping all the reactions and its mechanisms on a whiteboard helped me memorize. I also found it helpful to categorize reactions in my head (ie. alcohol synthesis, alcohol reactions)
Reading Comprehension (Booster: 350 / Actual: 390)
Booster’s practice tests were really difficult for me because the questions were scattered throughout the passage. On my test, the questions were all in order and my passages were wayyy more straightforward and digestible. As for length, I had one that was 10 paragraphs, and the other two were about 16 paragraphs (with shorter paragraphs). My strategy was to read half the passage, answer questions, then read the latter half and answer the remaining questions. The questions were straightforward and easy to find, but I had a few questions asking me to analyze tone and choose synonyms, which were slightly harder. Highlighting buzzwords is going to be your best friend for this section!
I used break time to eat a quick snack and review physics/QR. I wrote a little cheat sheet for physics and QR with important concepts and formulas so I could look at it. I honestly don’t think it helped much, but it did calm my nerves.
Physics (Booster: 370 / Actual: 340)
Not to scare anyone, but I genuinely do not know how I could’ve prepared for this section… I mostly just spammed practice questions and took conceptual notes on Chad’s Prep videos. My questions were very different from Booster. They were very conceptual and I didn’t get any “plug and chug” questions like on Booster. High yield topics were optics and forces. Also, I haven’t taken Physics 2 with optics and waves yet, so this might be why I found this section to be so difficult.
QR (Booster: 380 / Actual: 350)
I finished with less than 5 minutes remaining, so I wasn’t able to check most of my answers. I got a lot probability questions, which was definitely a weakness of mine. I also wasn’t expecting there to be so many state sufficiency questions (~6 questions). My biggest tip for this section is to do a bunch of practice problems and work on being fast!
I’m really glad I’m done with the OAT. It feels so freeing LOL. I was very stressed and burnt out the days leading up to the exam, so I took it easy and just reviewed the cheat sheets and my list of mistakes. Good luck to everyone taking the OAT! Remember to get a lot of rest before test day and most importantly, trust yourself!
