<p>I am using the new BB to prepare for SAT thats 2 weeks away. Thus far, I have taken the first 5 tests and noticed an interesting pattern. I did well on first 3 tests (at least 700 in each section) and improved from test to test. After that, on tests 4 and 5, my scores became extremely erratic and inconsistent (low 600s to low 700s). Now, the first 3 tests were actually administered at some point in last 3 years and thus they provide an accurate scoring scale. The last 7, on the other hand, is just a composure of questions by CB. When I took test #4 and received somewhat disappointing results, I thought it was just a fluke. however, after taking test #5, I conclude that my performance has fallen off for some reason. Could it be that the tests that were not administered have an inconsistent level of difficulty among the questions? I am at a loss trying to explain this phenomenon (will start taking test #6 tomorrow ;) ) Has anyone else had a similar problem?</p>
