The problem with most study schedules isn't the plan — it's that they're designed for a version of you that never gets tired, distracted, or behind.
A schedule with zero buffer time breaks the first time something goes wrong — and something always goes wrong. Leave one day a week genuinely unplanned, so a bad day doesn't cascade into a bad week.
Studying Physics for six straight days and then switching to Chemistry feels efficient, but spaced repetition research consistently shows that interleaving subjects improves long-term retention over blocked practice — even though it feels slower in the moment.
"I studied for 4 hours" and "I solved 40 problems with full attention" are very different claims. Log what you actually did, not just how long you sat at a desk.
If you're not reviewing questions you got wrong last week, adding more new material just means you'll forget both the old and the new. Weekly review time isn't optional — it's the thing that makes the rest of the schedule actually work.
