Timeboxing
Timeboxing means moving your to-do list into your calendar: "Chapter 4 reading, 7:00 to 7:50" instead of "read chapter 4" floating on a list with no time attached.
For evening study the gain is that the decision about what to do is made in advance, before you are tired, and a fixed end time stops one topic from swallowing the whole night. It also makes trade-offs visible: if three boxes will not fit before 10 p.m., you find out at the start of the week rather than at 9:45. Keep the boxes realistic and leave one empty slot for overruns, because a schedule that falls apart by 8 p.m. quickly teaches you to ignore it.
