Act prep and actual test prediction HELP!

<p>I used the REAL ACT book to prepare for the ACT that I am taking on April 12. I just took the fifth and final practice test from the book. I would appreciate any feedback if you have done the REAL ACT book. How well did you do on the actual test? My breakdown is this:
actual test with NO test prep October 2013: 28
Practice test 3/7/14: 30
Practice test 3/15/14: 27
Practice test 3/22/14: 30
Practice test 4/1/14: 29
Practice test 4/5/14: 32</p>

<p>Based on those scores, how do you think I will do on the actual test?
Any predictions are much appreciated as a 30 would be great but I don't want to get my hopes too high.
Thanks :) </p>

<p>My S practiced at home and his composite score in average was 27-28. In real test he got 30.
2 points higher can be predicted.</p>

<p>My daughter took 1 full length practice test the day before the real thing. She got the same composite score though the real math was lower and science and English were higher. She said the April math was a little harder than the practice tests in the red book. I’m sure it varies with every test. I’m not sure her composite would be much different if she took it again though the components would probably change. </p>
