I would tell business and economics students to come up with mnemonics as there is so much content to memorise such as statistics and case studies. Make it inappropriate even if you have to. At the same time, ask a lot of questions in class. This will improve your understanding, which is greater than ROTE learning. If you memorise, one missing link between the cause and effect will be the end of you. However, understanding will naturally form links between cause and effect because logic will fill in the gaps for you. Really take the given cloze passage and worksheets and use them for your study notes!!! They are really valuable because they contain the cause and effect + statistics + trends!
