Making your formula sheet is by far the best option. Also make a note of the relationship between the variables.
You will end up getting more concept questions that the number crunching. For the # qns (1) you surely needed the formula (so memorize inside out) and for the concept qns, (2) you need to know the formula, relationship and to some extend background (not a real derivation) of what makes the formula functional. Reason being, you will not see a formula but there will be a qn, where in you need to re-arrange the formula to get to the answer. Stalla lecture and notes gets deep in to the understanding part, use it well.
Dont worry a lot of schweser qns will be there too tune your thought process in solving these qns.
Expect more of Qn (2) types. they love it.
