Midterm #1 usually covers course content from the first lecture to the end of electron configurations. Your instructor will let you know the exact cut-off used in your semester.
The last page of every test is a double-sided data sheet which contains formulas, values for physical constants, a periodic table and the band of stability graph. It may also contain additional data such as exact masses of isotopes. A sample data sheet has been posted below. We recommend that you use it when solving practice questions to get used to the layout.
The practice tests should be used to self-test. Just reading them (or, worse yet, just reading the answer keys) is a waste of your time and denies you the learning opportunities available when they are used properly. Do a practice test with your books closed and time yourself. Only allow yourself the tools you would have on a real test (calculator and data sheet).
