Chemistry tuition, Class 9 and 10

Chemistry, like physics, is a unit within Science at this level rather than standing alone, and both appear on the same examination.

Class 9 covers matter's nature and states, mixtures and pure substances, methods of separation, atoms and molecules, and atomic structure. This is the foundational year—and its importance is quiet. Little content is inherently difficult, yet virtually everything provides the base for what comes next.

Class 10 introduces chemical reactions and equations, acids and bases, salts, metals and non-metals, and carbon compounds. This is when serious demands arrive. A student who was uncertain about valency in Class 9 will struggle to write correct formulas in Class 10—week after week.

This two-year progression clarifies the most familiar pattern of chemistry difficulty we encounter: a successful Class 9 followed by a significant drop early in Class 10. Class 10 chemistry is rarely inherently difficult. The real issue is that Class 9 chemistry was never completely mastered, because at the time it did not feel mastery mattered.

NCERT has updated its Class 9 and 10 Science content multiple times recently, and different schools use different versions. Our classes work from the exact table of contents in your child's textbook.

Three foundational ideas sit underneath almost everything else in Chemistry, and each one deserves your attention.

Valency and formula writing. Your child can memorise that calcium chloride is CaCl₂, or she can learn to build it from valencies. The first is one fact. The second means she can work out a formula for any compound nobody has taught her. That is chemistry; the first is memorisation, and memorisation will not carry her through Class 10.

Balancing equations. Most students learn this as a puzzle-solving technique, rarely as the principle underneath it—atoms cannot be created or destroyed, so the counts must balance. When your child understands the reason, she balances faster. More importantly, she notices when her answer cannot possibly be right.

The mole. This is the concept most often quietly skipped, and then it breaks everything downstream. A mole is simply a counting unit, like a dozen—a way to count particles by weighing them, because particles are too small to count directly. Once your child grasps this idea, mole calculations become arithmetic. Until she does, they are magic, and she works through them by copying patterns from examples.

There is a simple check for understanding the last one. Ask your child what a mole actually is. If she answers with a number rather than an idea, that is where you need to start.

Much of Class 10 chemistry is learnable through families of reactions. Your child who tries to memorise individual reactions has to remember dozens of separate facts. Your child who learns the families needs to remember just a handful of patterns and can then predict.

The main families are combination, decomposition, displacement, double displacement, and reactions involving oxidation and reduction. You also need to understand how acids and bases behave with metals, with carbonates and with each other, and the reactivity series, which tells you in advance which displacement will happen.

Once your child can classify a reaction at a glance, an unfamiliar equation stops being frightening. They may not know that specific reaction, but they know its family, and the family shows them what the answer should look like. This is when chemistry starts to feel manageable, and it is something that can be taught, not an innate talent.

Organic chemistry in Class 10 - carbon compounds - works the same way. Learn the structure and naming rules, and the compounds stop being a list to memorise and become a system your child can read.

Small batches, with every student writing equations in every class rather than watching one being written.

• Valency before formulas, always. If formula writing is unreliable, we return to valencies rather than issue a list to memorise.
• Reason before technique for balancing. Why it must balance comes first; the method follows and then makes sense.
• The mole taught as an idea. A counting unit explained with things students can picture, before any calculation is attempted.
• Reactions taught as families so unfamiliar equations become classifiable rather than overwhelming.
• Class 9 rechecked in Class 10. When a Class 10 student is struggling, we check Class 9 foundations first, because that is usually where the issue lies.

Chemistry also has an unusually high proportion of marks in precise notation - state symbols, conditions above the arrow, correct subscripts. These are easy marks to lose and easy marks to recover, so we mark for them from the start. Fees for group and one-to-one tuition are published in full, and the first class is free.
