The below image shows my study behavior in fall 2017-18. I have increased the study time during the semester. The increase, however, may be due to the fluctuations I experienced if the lab hours and assisting hours are included in the study time. To avoid this problem, I will itemize clearly which activities should and which should not be included in the study time.
The data for some weeks were not available because sometimes I had given up recording the study time during the week. The problem usually had happened in those weeks that I did make a plan for it ahead. It would help if I separate a distinct timeslot for planning the week.
If we exclude the weeks which data was not available for, it will more clear what was the regime of study during the last semester.
