thePsychology.ai vs AATBS: An Honest 2026 EPPP Prep Comparison
Adaptive EPPP prep, free for 7 days.
Full question bank and practice exams. No credit card. $30/month through June, $40 from July 1.
If you are studying for the EPPP, you have probably run into AATBS. It has been around since 1976 and most people who prep for this exam have heard the name. You are likely here trying to decide if it is worth the price, or if something newer fits you better.
I should be upfront. I am Anders Chan, a licensed psychologist. I built thePsychology.ai, so I have a stake in this. That is exactly why I want to be fair. AATBS is a real, established product with real strengths, and I will not pretend otherwise. Here is a straight comparison so you can pick what is right for you.
thePsychology.ai vs AATBS
| thePsychology.ai | AATBS | |
|---|---|---|
| Price | $30/mo now, $40 in July | $999 to $1,649 |

Where AATBS is strong
- Very large question bank, over 3,000 practice questions.
- Strong name recognition. It has been a known option since 1976.
- Structured, traditional study plans if you like a set path laid out for you.
Where thePsychology.ai is different
- A continuous adaptive loop. It recalibrates every session and brings back missed concepts from new angles until the material actually sticks.
- The lowest monthly price in this comparison, at either $30 or $40.
- A free 7-day trial with no credit card. You can try the whole thing before you pay a cent.
- Mindfulness and wellness tools built right into the study flow. This is unique in the category, and the EPPP is stressful enough to need it.
- Built by licensed psychologists who took the exam. I scored 588. The 80+ lessons are written by people who sat in the same chair you will.
I will also name my own weak spots. thePsychology.ai is newer, so the track record is shorter and the user community is smaller. There is no native iOS or Android app yet, just a mobile-responsive web interface. Users have reported that AATBS materials can feel dry and the platform looks dated, but AATBS has the longer history.
A quick note on price
Right now in June 2026, thePsychology.ai is $30/month. In July the price for new members goes to $40/month. Existing members keep whatever rate they joined at. So if you start now, you lock in $30. No pressure, just the honest math.
Who should pick what
Pick AATBS if you want the biggest possible question bank, a familiar name, and you prefer paying once for a fixed, structured plan you follow on your own.
Pick thePsychology.ai if you want studying that adapts to your weak spots, a low monthly cost, built-in tools to manage the stress, and lessons written by psychologists who passed the exam. It also helps if you want to try before you buy.
Either way, the right answer is the one that actually gets you to study and pass. Both can do that.
Try it yourself
The easiest way to know if thePsychology.ai fits you is to use it. You can start a free 7-day trial with no credit card, see how the adaptive loop feels, and decide from there. If you start in June, you lock in $30/month before it rises to $40 in July.
