When reviewing your work, think about the time that you have invested in different topics or tasks. If you spent a lot of time on a particular assignment, it is likely that you also found this difficult. Moreover, if you are not particularly proud of the work you submitted in a particular assignment, then it is likely that the quality was not good enough or that you did not succeed in your time management. These are the areas that would most likely benefit from a change in your approach for future weeks.
