Two-night chemistry timetable

You have 10–12 study hours total, so aim for strong first-pass preparation, not complete mastery. Give more time to Organic Chemistry and Chemical Bonding, because they are broader chapters.

Night 1 — Organic Chemistry, Chemical Bonding, and revision

Time	Task
9:00–9:15 PM	Set up books, list subtopics, keep phone away
9:15–10:45 PM	Organic Chemistry — Part 1: basic terms, homologous series, functional groups, nomenclature
10:45–11:00 PM	Break
11:00 PM–12:15 AM	Organic Chemistry — Part 2: important reactions, preparation methods, properties, equations
12:15–12:30 AM	Break/snack
12:30–1:45 AM	Chemical Bonding: electrovalent, covalent, coordinate bonds, electron-dot structures
1:45–2:00 AM	Break
2:00–2:40 AM	Practice equations, structures, and textbook questions
2:40–3:00 AM	Write a one-page recall sheet without looking at your notes

Night 2 — Ammonia, Acids–Bases–Salts, Sulfuric Acid, and final revision

Time	Task
9:00–9:15 PM	Recall Night 1 using your summary sheet
9:15–10:30 PM	Ammonia — Study of Compounds: laboratory preparation, Haber process, properties, reactions, uses
10:30–10:45 PM	Break
10:45 PM–12:00 AM	Acids, Bases, and Salts: definitions, indicators, pH, neutralisation, types of salts, important reactions
12:00–12:15 AM	Break
12:15–1:30 AM	Sulfuric Acid: Contact process, conditions, properties, oxidising/dehydrating action, uses
1:30–1:45 AM	Break
1:45–2:30 AM	Revise all important chemical equations and conditions
2:30–3:00 AM	Solve mixed questions and mark weak areas for later revision

How to study each chapter

Use the same four-step cycle:

1. Read for 25–30 minutes.
2. Close the book and recall the key points for 5 minutes.
3. Write important equations and definitions from memory.
4. Solve 3–5 questions before moving on.

Do not spend the whole night making neat notes. Prioritise definitions, conditions, observations, chemical equations, diagrams, uses, and board-style questions. Sleep after 2–3 AM; memory and recall will be much weaker if you continue all night without rest.

Two-night chemistry timetable

This plan covers Periodic Table and Periodic Properties, Chemical Bonding, Acids–Bases–Salts, Analytical Chemistry, and Mole Concept and Stoichiometry from 9:00 PM to 3:00 AM. The heavier chapters receive more time.

Night 1 — Periodic Properties, Chemical Bonding, and Mole Concept

Time	Task
9:00–9:15 PM	Prepare books, water, calculator, and a short task list
9:15–10:30 PM	Periodic Table and Periodic Properties: modern periodic table, groups and periods, valence electrons, atomic size, metallic character
10:30–10:45 PM	Break
10:45 PM–12:15 AM	Variation of Properties: atomic radius, ionisation potential, electron affinity, electronegativity, and trends across periods and down groups
12:15–12:30 AM	Break
12:30–1:45 AM	Chemical Bonding: electrovalent and covalent bonds, formation of ions, electron-dot structures, properties of ionic and covalent compounds
1:45–2:00 AM	Break/snack
2:00–2:40 AM	Mole Concept and Stoichiometry — Part 1: mole, Avogadro’s number, molar mass, percentage composition
2:40–3:00 AM	Write formulas and solve 3–5 basic mole-concept questions from memory

Night 2 — Mole Concept, Acids–Bases–Salts, and Analytical Chemistry

Time	Task
9:00–9:20 PM	Revise Night 1 using your recall sheet; do not reread the whole chapter
9:20–10:35 PM	Mole Concept and Stoichiometry — Part 2: chemical equations, mass–mass calculations, volume calculations, limiting reactant basics
10:35–10:50 PM	Break
10:50 PM–12:05 AM	Acids, Bases, and Salts: definitions, indicators, pH, neutralisation, types of salts, preparation and important reactions
12:05–12:20 AM	Break
12:20–1:35 AM	Analytical Chemistry: tests for cations and anions, observations, precipitates, colour changes, and confirmatory tests
1:35–1:50 AM	Break/snack and short walk
1:50–2:30 AM	Revise all important equations, trends, tests, colours, and conditions
2:30–3:00 AM	Solve a mixed test: 2 periodic-trend questions, 2 bonding questions, 2 mole calculations, 2 acid–base questions, and 2 analytical tests

Priority order

If you fall behind, study in this order:

1. Mole Concept and Stoichiometry
2. Chemical Bonding
3. Analytical Chemistry
4. Periodic Properties
5. Acids, Bases, and Salts

For Analytical Chemistry, make a compact table with ion/test → reagent → observation → conclusion. For Mole Concept, spend more time solving problems than reading theory. Stop by 3:00 AM, sleep properly, and review the recall sheets the next day.

Two-night chemistry + mathematics timetable

Study from 9:00 PM to 3:00 AM. Each block follows this pattern:

Chapter name → short lecture → notes → active recall/practice

Do not watch long lectures. Keep each lecture to 25–35 minutes, then immediately write notes.

9:00–9:10 PM	Set up books and write tonight’s targets
9:10–10:25 PM	Periodic Table and Periodic Properties — 30-minute lecture, 35-minute notes, 10-minute recall
10:25–10:40 PM	Break

2:20–2:30 AM	Break
2:30–3:00 AM	Revise all three subjects: write periodic trends, matrix formulas, and bonding definitions without looking

Night 1 note-making format

• Periodic Properties: make a trend table for atomic size, ionisation potential, electron affinity, and electronegativity.
• Matrices: write each formula and solve one example beside it.
• Chemical Bonding: draw electron-dot structures and list ionic versus covalent properties.

Use this method inside every study block

1. Read the chapter name and objectives: 2–3 minutes.
2. Watch one short lecture: 25–35 minutes.
3. Complete notes immediately: definitions, formulas, reactions, diagrams, and examples.
4. Close the lecture and book: recall the main points for 5–10 minutes.
5. Practise: solve questions instead of repeatedly rereading.

Because seven chapters cannot be mastered deeply in two nights, your target should be one complete first revision plus important questions, not perfect memorisation. Protect the final 15 minutes for recall rather than extending study beyond 3:00 AM.
