So I used the TPR science workbook and I looked at their solubility rules, and although it is accurate, it is a shorthand version of all the long and tedious solubility rules. For the MCAT (im a re-taker) on practice tests and the actual exam, I've seen some problems which require a more in depth knowledge of the solubility rules than those provided in the TPR. Yes, I know the MCAT tests BASIC knowledge but is there a more detailed version of the solubility rules that I should have memorized.

TPRs say that

1. All group I metals and NH4 salts are soluble
2. All acetates (CH3COO-), nitrates (NO3-) and perchlorates (ClO4-) are soluble
3. All silver (Ag), lead (Pb), and mercury (Hg) salts are insoluble EXCEPT if they are with the acetate, nitrate, or perchlorate.

will this suffice? can anyone provide a more adequate set of rules?

Salts containing halides are soluble except for heavy metals you listed.
SO4 is soluble except for heavy metals and SrSO4 and AgSO4
CrO4 is insoluble except for group 1.
Sulfides are insoluble except for group 1 and 2.
Oxides are insoluble except for group 1 and 2.
CO3 and PO4 are insoluble except for group 1
