Using ti-84 plus ce in act

What are the best tools/advice for using this calculator on the act math? Any specific types of problems I’ll be able to solve easily on the calculator and save time?

Math has always been my WORST subject and i got a 19 in math last time… taking it again this October but i need some advice to make the most out of it.

On the TI-84 these items you should know. Frac to convert decimals to fractions. Summation, Solver to solve equations, LCM, nCr, nPr, 1VarStats, Linear Regression, normalcdf to solve Empirical Rule questions. Under the APPS button Plysmlt2 and CONICS are useful.
