Midterm #1 usually covers course content from the first lecture to the end of valence bond theory.  Your instructor will let you know the exact cut-off used in your semester.

The last page of every test is a data sheet which includes a periodic table.  It may also include other relevant data such as physical constants and/or formulas. 

Whether or not calculators will be permitted on midterm #1 for CHEM 2000 will be at your instructor's discretion.  Typically, they will only be allowed if the instructor is considering including at least one calculation on the test.  It is expected that students are able to perform very basic arithmetic (e.g. multiplying by 1, 2 or 10) without the help of a calculator.

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).
