4R was significantly harder than 3R. Anybody know how the rest compare?
I took all 5 aamc tests, and will say that 3R is the easiest one which is probably why it is the ONLY FREE test offered by aamc.
Anyhow, I believe that test 4R and test 7 were more representative of the level of difficulty of the real test. Test 7 was an actual MCAT, not revised test like 3R, 4R, 5R, and 6R.
It is also the most recent practice test released by the aamc. Its level of difficulty was harder than the real MCAT I took in August 2004, and its verbal was by far the hardest Verbal from any practice test I have taken. That is taking into account that I have not done tests A-D.
Tests A-D are much harder from what I hear than other tests. I will be taking them soon as well as 4941, 4951 and 4961.
Anyhow, hope that helps you. If you are averaging 34's and above right now, after having taken 3 or 4 practice tests, and 39 on 3R, then I'm sure you'll be getting a 35 or above on the real deal. Take test 4R and 7 and those should give you a real indicator of where you stand for real test day in my opinion.
Also, in my opinion in terms of level of difficulty, the aamc tests rank from easiest to highest as follows:
3r easiest
5r/6r slightly harder than 3r. Involves a bit of math.
4r slightly harder than 5r/6r
7 hardest
Hope that helps.
