Break your workload into visible tasks: read a section, solve a set of problems or revise a topic. Use priorities to choose what comes first.
With Plus, give each task a planned date and an estimated number of Pomodoros. Leave room for breaks and use the weekly view to move work between days.
Select a task, focus, then mark it complete when the work is done. Revisit unfinished tasks instead of deleting them. Session history helps you see where your time went.
