I just spent the last 15 minutes of my life trying to recall what I had once completely memorized my junior year of high school: the periodic table. I remembered plenty of obscure elements and forgot some of the most obvious ones. If only I had a chance to review before I took the test, I probably would have gotten twice as many. Don't cheat. Name as many as you can in 15 minutes. Just start typing the element names in and if entered correctly they will appear in the table.
