Awesome job!
I really found getting information from multiple sources useful. The more times you see and hear a concept explained, the more likely you are to remember and retain it in detail.
One other thing that I think a lot of people forget other than task words, is to actually answer the question. If a question is "Discuss how the implementation of performance related pay would affect the productivity of staff at Felix's Bakery?". Not only would you explain advantages and disadvantages, but you would need to explain how this would positvely/negatively impact productivity. Finally, as a business or business owner is mentioned, you must also refer back to the case study in some capacity to ensure the question is actually answered and you have not just regurgitated some rote learned benefits and weaknesses of a concept.
