I’d go with:
DAT Booster - $250
DAT + Math Destroyer Bundle - $200
The other option you’ll see most people suggest is:
DAT Bootcamp - $500
You get better resources and more practice questions with the first option imo and you pay less.
you can find breakdowns where people didn’t use any of these resources and were successful. Not sure what they did but it worked for them and may be worth looking into.
You can use some of DAT bootcampa free resources like their 120 of bio notes for quick review, but I wouldn’t say their $500 or $1000 option is worth the price.
Destroyer isn’t representative of the actual DAT, it’s much harder but it exposes you to all the material and prepares you for anything you could see. It’s not a content review resource though, it’s more of a practice and knowledge/understanding check. Most people will use either Feralis notes (now incorporated into DAT Booster), or Orgomans Dynamite Bio notes for bio content review and then Chemistry Review videos from Chad or DAT Bootcamp or DAT Booster as a base before starting through Destroyer. And most people scoring 22+ are going through Destroyer multiple times.
Bootcamp and Booster are supposed to be a “one stop” package. Content review, practice questions, timed practice tests to help simulate the real thing. I don’t think Bootcamp offers anything more to justify the $250 price difference. Especially when I can use the money saved to get The Destroyer books and still end up saving $50.
