Memorising Solubility Rules (1 Viewer)

Hi all, does anyone have any tips for efficiently memorising the solubility rules for chem? Would it be helpful to create some kind of table? It's a little frustrating to just rote learn it for exams

This may not be the best approach, but I think the SNAAP rule and the solubility values on the formula sheet (remember, the smaller the ksp the more insoluble it is) are probably the first most useful resources.
