Have you a good business studies book and notes taken down? Usually best to look at exam papers and look up the answers youre not sure of from your textbook. Calculations you may need some one to one help with, always good to practice those out of your workbook.
it depends on what type of learner you are for example visuals might be better for you than just being told or visa versa, i recommend you try to figure out what type of learner you are before anything else and work form there but if you rather just try to move on take any notes you where given and write them out in the plainest way possible so that your brain isnt bogged down by words you dont fully understand.
I used to watch a lot of youtube videos if you look up tge topic you are working on you can usually find a youtube video also Pick one topic and do the questions that are on studyclix and then check answers hope this helps
