How can I study hard for a test from my class NOTES ive been writting down?

May is the CST and Im homeschooled through K12 CAVA.Ive written notes down as I go through lesson but right now,I just dont feel like ive learned anything.Im in 7th grade.I thinks it becuase I just write the notes down and skip the homework with going through the lesson and trying it out and doing some problems.Boy i really wish I could rewind because I have a huge cst test in 2 months.I cant go back cuz its to far.So is there a way I can study from my notes.Find some problem for example...Pre-Algebra.If Im onnnn.saaayyy.Multiplying fractions could I look online for mutliplying fractions promblems and try those out? Something !!?!?! anything??
