my average qvault scored equaled my real DAT score.
I don't know why people hate on its qr and oc section. Their BIO,GC,QR,PAT are on point with BIO being a gold mine...also i feel like they are updating it? because I looked over it while helping my friend taking the dat soon and it has changed since I was using it a month ago.
I think bootcamp really requires you critically think when the DAT is a lot more straight forward. That is my take on it. However, the conceptual GC questions are very well written on bootcamp and QR was a good challenge for me. Qvault seems very straightforward in most of their questions and is actually similar to the real test.
I would still buy both though, both are great products to be honest... what is $100 worth when this one test determines whether you get accepted/rejected.
