<p>My son’s experience is what Benny B described. Years ago he took the chem after non-AP chemistry and scored the 730. His best friend waited a year and took it after Ap chem and scored much lower.</p>
<p>The one comment in reverse was with my daughter this past year. She was supposed to take the Math I/II last June. At the last minute, we had her opt out. She ended up having to take it in October during her senior year after she started Ap Calc. After taking the Math II she was glad she had not done the test in June since there were certain topics that were covered in the beginning of AP Calc that she did not know and were on the test.</p>
