Set the weekly windows you are genuinely free to study, then block out the trips, shifts and exam days that take them back. That, minus the interruptions, is your capacity.

Each task carries an estimate, a priority and a due date. Add them up across the next week and you have the other half of the sum — the hours you owe.

Add the weekly windows you can study, and block out the days you cannot.
Every task gets a deadline and an estimate of how long it will take you.
One figure: the hours you are short, or the hours you have spare. Change something while it still helps.
