Two exams on Friday: statistics at 9 AM, economics at 2 PM. Most students respond by studying both every day in alternating panic, then cramming economics during the lunch gap. That's how both exams end up mediocre — not from lack of hours, but from two subjects interfering with each other at the worst possible moments.

The real problem isn't time — it's interference

Studying two subjects on the same day isn't twice the work of one; it's different work. The danger is similar material blurring together — the stats formulas and the econ models colonizing each other — and the deeper danger is attention residue: every switch costs a chunk of the next block to re-load.

That changes the strategy. The question isn't "how do I fit two subjects in" — it's "how do I keep them from stepping on each other." Three rules handle most of it: day-sized alternation (not hour-sized), asymmetric investment (the weaker subject gets the deep work), and a hard rule about the exam-day gap.

The week-of split

Work backwards from exam day. The second exam gets a built-in advantage — a whole extra review window on exam day — so it doesn't need the night before.

When both exams live in the same week, generation speed is the bottleneck — you can't afford to spend half of stats day writing questions. If the course material is already in LearnX, each subject's Exam Sprint produces its own Study Units and practice questions, so a "subject day" is doing the sprint, not building it.
