Its not about the important formulaes, its about the logic which you develop in Physics.

Start with the topic with which you are familiar. Read there theory once and And start doing questions in a big amount. Be aware that those topic carry more weightage in exams. Once you are done with this stuff, start doing random questions( like mock papers). 

And for the important formulaes which you want, buy a handbook of Physics which contains all important Formulaes.
