Study Planner — Schedule Subjects, Sessions & Exam Prep
Plan study sessions across subjects with daily / weekly schedules, exam countdowns, and progress tracking. Free, in-browser.
About Study Planner
A study planner is a structured schedule that allocates specific time blocks to specific subjects or tasks across days and weeks leading up to exams or deadlines, replacing the unrealistic "I will study a lot tomorrow" intent with concrete, finishable sessions. The ZTools Study Planner runs entirely in the browser, lets you list subjects with priority + estimated hours, generates a daily / weekly schedule respecting your available study windows, tracks completion of each block, supports exam countdowns with auto-allocation against the exam date, and persists everything in browser storage so closing the tab does not lose your plan.
Use cases
- Final-exam prep over 4 weeks. Five exams, 80 hours of material total, 4 weeks until first exam. Planner allocates ~20 hours / week across subjects in priority order, weighted by exam date proximity.
- Weekly course load. During semester, plan 15 hours / week of study across 5 courses. Daily 1-2 hour blocks per subject; weekend catch-up sessions for trailing topics.
- Standardised-test prep (SAT, GRE). Months out from test day, allocate practice tests + content review + flashcard time. Countdown view shows progress vs schedule.
- Group-project deadline tracking. Project broken into milestones; each milestone gets its own block in the planner. Avoids the night-before sprint by spreading load.
How it works
- List subjects + priorities. Subject name, total estimated hours, exam / deadline date, priority (1 highest).
- Set available study windows. Per day: which hours are available (e.g. weekdays 7-9pm, weekends 10am-4pm).
- Auto-generate schedule. Planner allocates blocks across windows by priority + deadline proximity. Higher-priority subjects get earlier and more frequent slots.
- Mark blocks done. After each session, mark complete. Planner shows progress bar per subject (hours done vs total).
- Adjust on the fly. Missed a session? Re-run the auto-allocator on remaining time; it redistributes the unfinished hours into upcoming windows.
Examples
Input: 5 subjects, 80 total hours, 4 weeks, 20 study hours/week
Output: Schedule: 4 hours / day Mon-Fri; 50 hours allocated to top 2 subjects (most weight), 30 across remaining 3.
Input: GRE prep: 100 hours over 12 weeks
Output: ~8 hours/week — split into 4 sessions of 2 hours; weekly practice test on Sunday.
Input: Missed 6 hours this week
Output: Replan adds ~1 extra hour / day for the next 6 days to catch up before falling behind further.
Frequently asked questions
How accurate are the time estimates?
Most students underestimate by 30-50% on first plan. After 1-2 weeks of tracked sessions, recalibrate — the planner shows actual vs estimated hours per subject.
What if a subject takes longer than planned?
Adjust total estimated hours up; planner reallocates remaining time. Better to update the plan than to silently fall behind.
How do I handle multiple exam dates?
Each subject has its own deadline. Planner front-loads earlier-dated subjects without ignoring later ones — the priority weighting handles this.
Is this just a calendar?
No — a calendar shows time. A planner allocates time-to-subject by priority and reflows when life intervenes. Calendars complement planners, they do not replace them.
Should I include breaks?
Yes — for blocks longer than 60 minutes, factor in a 10-15 min break (Pomodoro-style). The planner can model breaks; otherwise, account for them mentally.
Why not just list to-dos?
To-do lists do not constrain time. A planner forces you to confront whether the to-do can fit in the available hours — usually exposing wishful thinking early.
Pro tips
- Replan weekly. Plans built today rarely survive contact with reality past 5-7 days.
- Schedule the hardest subject first in the day — willpower and focus deplete with hours awake.
- Leave 10-15% of weekly time as buffer — illness, social commitments, broken assumptions all happen.
- Track actual hours, not just check-marks. Hours of distracted "studying" do not count the same as deep-focus hours.
- Print the weekly plan and tape it where you sit to study — visible commitment beats hidden intent.
