How Much Can I Save Using An OAT Booster Discount Code?

Our reader code TESTPREPPAL gives you 10% off any membership. Here is what that saves against OAT Booster's 2026 pricing:

A standard 10% code saves roughly $60 on the 90-day plan and about $100 on the 180-day plan. During the biggest holiday sales, that can climb toward 15% off. Prices change during sales, so confirm your final total at checkout.

The Higher Score Guarantee

OAT Booster backs every membership with a Higher Score Guarantee. If you follow the program and your official OAT Academic Average does not improve over a previous official OAT, Booster gives you the choice of a free 90-day extension or a 50% refund. You need to meet Booster's usage requirements and provide official score documentation from both attempts to qualify. For retakers especially, it is real protection on your spend.

How Often Does OAT Booster Run Special Promotions?

The OAT Booster 10% off sale runs pretty much all year round, and there are a number of working promo codes that you can use to unlock this offer, such as 'TESTPREPPAL', for instance.

Aside from the regular 10% off OAT Booster sale, the company will occasionally run its 15% and 20% off sales during special holiday sales such as Thanksgiving Black Friday sales, etc.

You could always regularly check their website to see if there is any special promotion running.

But an even more efficient strategy would be to enroll in their mailing list so you can always stay up to date with all the best promo codes the minute they are released.

If these special promotions don't seem forthcoming at the time you may wish to enroll for an OAT Booster course, then you could always reach out to the OAT Booster team requesting for a coupon code and they will gladly oblige.

Also, another thing to keep in mind is that during their special promotions, OAT Booster will typically combine cash off along with additional subscription days.

For instance, you may find a holiday deal that pairs a price cut with a handful of extra study days, so you get more time on the 90-day plan for less than the standard price.

Saving some cash and picking up extra study days is a nice combination if the timing lines up.
