Ooh, we get to compare. Well, we have to take yearly TCAP tests all through elementary school, so that is 5 (kindergarteners get a free pass), plus 3 years of middle school, then I got another one in VA for the second half of 8th grade; High school had just 3 (2 in VA, 1 in TN because they wouldn't let me graduate, it was a freshman test, I was a senior. Let's just say it wasn't hard), ACT, SAT II (but no SAT, Washington and Lee requires it for college admissions), ACS tests in O Chem, P Chem, and Analytical, MCAT, GRE, ACS tests again in grad school, this time one in inorganic as well, NBME in anatomy, biochem, physiology, histology, neuro, micro, pharm, medicine, surgery, psychiatry, OB/GYN, peds. Thankfully the Steps aren't bubble tests anymore.
I am always tempted to start using black ink (and I have for some tests).
