A clean backward-planned schedule for one exam falls apart the moment a second or third exam lands in the same week — there's no longer one subject to front-load, there are several competing for the same limited hours. Here's what a university study-skills center recommends for ranking and splitting that time, and what the research on interleaving says about studying subjects side by side instead of one at a time.

The University of Pennsylvania's Weingarten Center lays out a four-step process for exactly this situation. First, rank your classes — by which exam is soonest, which matters more for your major, or which is just plain harder and needs more attention — rather than giving every subject equal time by default. Second, split your actual study time roughly 30% review (skimming notes and slides you've already learned) and 70% active practice (working old midterms, problem sets, or past questions), weighted toward doing over rereading.
Third, cap individual study tasks at around three hours each — a single unbroken block longer than that tends to lose focus rather than gain ground. Fourth, build an actual hourly schedule (Google Calendar, iCalendar, or a paper template all work), alternating subjects rather than stacking one after another, and building in real breaks and meals so the plan survives contact with an actual week rather than collapsing by Wednesday.
Alternating which subject you study, rather than finishing one entirely before starting the next, has a name in learning research: interleaving. Duke University's Academic Resource Center frames the basic case for it simply — "tests and exams typically do not follow the order in which the content was covered in class," so training yourself to switch between topics mid-session matches how you'll actually need to retrieve the material later, rather than retrieving it in the same fixed order you originally learned it in.
Rohrer, Dedrick, and Burgess's 2014 classroom study put a number on the effect: interleaved practice nearly doubled scores on a test given one day later, compared to blocked practice where students worked through one problem type at a time. The mechanism isn't just repetition — interleaving forces you to choose the right strategy for each new problem or topic as it comes up, rather than running on autopilot because you already know what category you're in, which is exactly the harder, more effortful retrieval that tends to produce more durable learning. A separate study by Kornell and Bjork (2008), using paintings from different artists rather than academic material, found the same pattern holds outside typical classroom content: "interleaving exemplars of different categories can enhance inductive learning" — in their case, recognizing which artist painted a new, unseen piece.
Combine the two: use the Weingarten Center's ranking to decide which subject gets the biggest blocks and which gets the lighter ones, then use interleaving inside each day rather than giving one subject the whole day and the next subject the next. A practical version of this, adapted from interleaving guides aimed at single-subject revision: list the topics you need for each exam, assign up to three topics per study session rather than one, spend roughly 20 minutes per topic within a session, and change the order of topics from session to session so your understanding doesn't quietly depend on the order you originally learned things in.
StudyPilot's exam planner is built around entering one exam at a time — its date, subject, difficulty, and the topics you need to cover, optionally with your own lecture notes attached as a PDF, DOC, DOCX, TXT, or PPTX — and it lays out a day-by-day, backward-planned schedule for that exam specifically. For a week with two or three exams, the honest way to use it is to build one plan per exam and then interleave the resulting blocks yourself across the week, the way the research above describes, rather than expecting the tool to merge separate subjects into a single automatically-interleaved calendar — it doesn't currently do that merge for you.
Enter each exam's date, subject, and topics into StudyPilot's exam planner, then interleave the day-by-day plans it builds across your exam week instead of studying one subject at a time.
