Predicted study times

How predicted study times work.

The diary uses your real pace, focus minutes and goals to forecast the hours you still need — and breaks them into a daily target so you always know what 'enough' looks like today.

  • Personalised pace based on your real focus minutes, not raw time
  • Per-subject hour forecasts that update after every session
  • Daily targets that flex around your other subjects and exams
  • Honest 'on track / behind' status — no false reassurance

"I went from cramming the night before to doing two hours a day, every day. My predicted grade jumped two levels — and I wasn't even stressing."
