How to revise for competitive exams without only rereading notes

After learning percentages, write three prompts: “What is the base quantity?”, “How do I find percentage change?” and “Why does a 20% rise followed by a 20% fall not return to the start?”

Answer without looking. Then compare with the lesson. If you cannot explain the base quantity, review that idea before attempting a faster shortcut.

For vocabulary, recall a meaning and sentence. For reasoning, rebuild the diagram. For GK, answer a specific fact prompt. Choose a task that resembles the skill you need in questions.

A convenient starting schedule is the next day, then 3, 7 and 14 days after learning. These are suggested reminders, not a scientifically fixed best interval for every student.

If you struggle at a review, repair the lesson and revisit it sooner. If a topic is easy across several reviews, give it a longer gap. Near an exam, adapt the schedule to the time available.

The free revision planner creates these dates and exports them to a calendar. It does not claim you have mastered a topic just because a reminder is complete.

Start with a quantity of 100. A 20% rise makes it 120. A 20% fall from 120 subtracts 24, leaving 96. The total change is a 4% fall.

The second percentage acts on a new base. That is the idea worth recalling. Memorising “20 minus 20 equals zero” fails because it ignores the changed base.

For a review, change the starting quantity to 250. The same changes produce 300 and then 240, still a 4% fall. Explain why before opening percentage notes.

For a non-numeric topic, use an equivalent check: create a new sentence for a grammar rule or redraw a seating diagram from its clues.

Review due topics before starting more new topics. Give weak ideas more attention than facts you recall easily.

When a backlog builds, group related items. For example, review five percentage errors together instead of creating five large revision sessions. Keep a short prompt for each error.

If you keep forgetting the same step, rereading the whole chapter may be inefficient. Write a tiny worked example for that step and solve a similar question. Use the error notebook to record the repair.

Once a week, retry a mixed group of old errors without solutions. Record which you solved independently, which you guessed, and which still needed help.

Use that result to adjust next week's reviews. A completed calendar entry records effort; an independent correct solution provides better evidence of progress.

Use formulas as recall prompts and topic practice to check application. Keep both parts: knowing a formula and choosing it in a question.
