A big part of being able to understand mineral processes, and to think intelligently about rocks you come across is to understand the mineral compositions. For example, you might not be able to identify a mineral in a rock conclusively without lab tests (say, talc vs. pyrophyllite), but by knowing the other minerals in the rock and their compositions, you can make a good guess in the field (because phlogopite is present, it's probably talc, since both phlogopite and talc have Mg).

By the final exam, you should know the compositions and/or formulas for these minerals. For those in which you are to know compositions only, I want you to know which elements or ions are in the structure, but not necessarily the relative amounts of each. For all the minerals you should also know the chemical group (e.g., borate, silicate, sulfide), the mineral group if it is a member of one (e.g., magnetite is a spinel, forsterite is an olivine, phlogopite is a biotite). For the silicates, you should also know the structural group (quartz is a framework silicate).

Note that for some of these, we do not have good samples, so they are not included in the list of minerals that you should be able to identify by the time of the Lab Final.
