Yes!

I HIGHLY recommend using this app and TBAS Study Pro. They’re different, and I think using both will give you the best tools you need to prepare for this test. I genuinely believe Alex wants to help people.

I started with this app, then later used TBAS Study Pro, and eventually came back to this app. After using TBAS for a while, my scores on this app soared. There are so many great things about both apps that I honestly can’t say which one I like more. They’re both great for preparing for the PBM section of the ASTB.

The only thing I struggled with was the math and reading portions of the test. I don’t know why, but on my attempts, it felt like nothing I studied for math was actually on the test. But if there’s one thing that can absolutely take me out, it’s math lol.

I’ve also read a lot of reviews saying that the reading section is probably the hardest section to study for. On this app, I was scoring in the 90s on the reading portion, but on the real test, I did not do as well. The questions threw me for a loop.

I actually think the aviation questions on the real test are easier than the practice questions on this app, but I felt overprepared going into that section.

Response from developer

Thank you for writing this out. A detailed review from someone who has actually sat the test is worth a lot. You are right about reading; the real RCT is dry Navy regulatory prose with two answers that differ by a single word like "may" versus "must." A lot of our older passages read like magazine articles, which is more interesting but trains the wrong skill. I have been rebuilding that whole section around real Navy document language; the first batch is already in the app, and the old-style passages are being retired as replacements land. On math, I'm always trying to improve it. And good to hear aviation felt easier on the real thing. Overprepared is the direction I want my clients to go down. As for TBAS Study Pro, no argument from me. Different tools, same goal, and a little friendly competition keeps us both sharp. Use whatever gets you the score. Good luck out there, Alex Hastings

67 9/9/9 on first attempt

This app was my primary tool to study for the test, and it prepared me better than I could have asked for. The PBM practice got me more than ready for the actual test, and the academic sections are dynamic and challenging just like the real thing. If possible, I would recommend going out and getting an x52 or a similar flight stick to pair with the windows/Mac version of the app. This will absolutely prepare you for the pbm. This app was absolutely worth every penny, and if you want it badly enough, this app will get you there.

Biggest help when prepping for the ASTB

I used pretty much every feature on this app while studying for the ASTB and it helped me a ton. The math, mechanical, ANIT, and PBM practice were really helpful and made me feel much more prepared going into the actual test. Being able to practice everything in one place and not having to jump around was probably the biggest thing for me. After taking the ASTB, I definitely feel like this app prepared me well for what to expect. I would 100% recommend it to anyone getting ready to take the ASTB, and this will be the first resource I send to anyone who asks me for help preparing for it.

I would definitely recommend the training session with Lou, he gave me great tips and advice and even remembered the day my exam was and took the time to follow up

Thank you so much for the review, Kooper! I’m really glad to hear ASTB Prep helped you feel more prepared going into the exam, especially across the Math, Mechanical, ANIT, and PBM sections. I’ve put a lot of work into making the app a complete resource so you can prepare in one place, so it means a lot to hear that it was valuable for you. I’m also really happy to hear your training session with Lou was helpful. I’ll make sure he sees your feedback! Congratulations on getting through the ASTB, and thank you again for recommending ASTB Prep to future test takers. Best of luck with everything moving forward.

Great Apl

Got accepted as a BDCP SNA with 50 6/8/7 on my first attempt using only this app. Would have easily gotten a near perfect score with other resources -such as the OAR app- but this app is in general the best and most up to date app on the market - worth every penny.

Also had the opportunity to do a coaching lesson with Lou. Great guy who takes his time to answer your questions thoroughly.

Overall, this app is incredible, with the all the flight portions being identical to the real test. If you want to pass, buy this app.

The best option if you need direction to start your naval career.

I have prior service in my family but no Navy or Pilots. I started with this app since it was the only thing I could find once my recruiter told me “study for the ASTB”. I got a 6/7/7. And I am on my way to OCS as a Pilot select. I would not have been able to do this without the guidance of Lou. He was always willing to pick up the phone and be a mentor no matter how hard or long the process has been so far. I recommend this app to anyone willing to get started as a SNA OR SNFO. Just be ready to do the work
