Study Planner

Split your weekly study hours across subjects by priority.

One per line. Add a weight after a colon for harder subjects — e.g. Calculus : 3

Time is split by weight, then grouped into 25-minute focus sessions.

To split your study hours across subjects, give each one a difficulty weight, then divide your total weekly hours in proportion to those weights. A subject weighted 3 gets three times the time of one weighted 1. The planner groups each subject’s hours into 25-minute focus sessions you can actually start.

Turning subjects into a balanced week

Listing your subjects is easy; deciding how much time each deserves is the hard part. Enter one subject per line and, after a colon, an optional weight for the harder or higher-stakes ones — for example Calculus : 3. The planner divides your total hours in proportion to those weights, then groups each subject’s time into 25-minute focus sessions.

Weights are relative, not absolute. A subject weighted 3 gets three times the hours of one weighted 1; leave the weight off and it defaults to 1, giving an even split.

subject hours = total hours × (subject weight ÷ sum of all weights)

hours round to the nearest quarter; sessions = hours × 60 ÷ 25

Worked example

15 hours across Calculus (3), Organic Chemistry (2), History (1), and Spanish (1):

  1. 1
    Add up the weights. 3 + 2 + 1 + 1 = 7 total weight.
  2. 2
    Give each subject its share. Calculus = 15 × 3/7 ≈ 6.5 h, Organic Chemistry = 15 × 2/7 ≈ 4.25 h, History and Spanish ≈ 2.25 h each.
  3. 3
    Split hours into 25-minute sessions. Calculus 6.43 h × 60 ÷ 25 ≈ 15 sessions; each subject rounds to whole sessions, at least one apiece.

A rough guide to weekly hours

A common starting point is 2–3 hours of independent study per credit hour, per week — adjust to your goals.

Making the plan stick

Set weights by difficulty and stakes, not by how much you enjoy a subject. The course you find hardest, or that counts most toward your grade, earns the higher weight.

Plan in sessions, not vague hours. “Four Calculus sessions” is something you can actually start; “study more Calculus” isn’t. The session counts give your week concrete, checkable blocks.

Set the total to what you really have. Planning 30 hours you’ll never find just hides the shortfall. An honest, smaller total spread well beats an ambitious one you abandon.

Run each block on a Pomodoro timer to keep the sessions focused, and check an exam countdown so the hours you set match the days you actually have left.

How do I add a weight to a subject?
Put a colon after the name and a number, like “Calculus : 3”. Weights are relative — a 3 gets three times the hours of a 1. Leave it off and the subject defaults to weight 1.
How are the hours split?
Each subject gets total hours × its weight ÷ the sum of all weights, rounded to the nearest quarter hour.
Why does it show sessions instead of just hours?
Attention fades over long stretches, so hours are grouped into 25-minute focus sessions — short, checkable blocks you can actually start.
How many hours should I study?
A common guideline is 2–3 hours of independent study per credit hour per week, but adjust to your goals and deadlines.
Can I plan around an exam date?
Set your total to the hours you have before the exam, and the planner shows how to divide them across subjects.
Why does a subject show at least one session?
Every listed subject gets a minimum of one session so nothing drops off the plan entirely, even with a small weight or few total hours.
