# A chemistry tutor: that balances the working

**The short answer.** Tutix teaches chemistry live: the AI tutor explains an idea, works equations and calculations with you on a shared whiteboard and reads your answer as you write it. Ready-made programs cover AP Chemistry and IGCSE Chemistry, Core and Extended, and any other course can be taught from your own notes.

- Live, spoken, one-to-one
- Your working is read while you are in class
- 2 ready-made programs
- Free plan: 45 live minutes a month

## How a chemistry class works

A Tutix class is a live, spoken lesson one-to-one with an AI tutor. For chemistry:

- Particles first. You explain what the particles are doing before you write the symbols.
- The mole, step by step. Mass, moles, ratio, answer: each line checked.
- Equations balanced properly. Changing a number in front, never a formula.
- Command words. The tutor teaches what "describe", "explain" and "calculate" each ask for.

A class, opened. A sample written to show how a class sounds (not a real learner); the scores show how the exam would credit each answer.

> **Equations · Balancing.** Question: Balance: Mg + O_2 → MgO
> The student wrote: Mg + O_2 → MgO_2 (the exam would credit 0 of 2)
> The tutor: You can never change a formula to balance an equation, only the numbers in front. Magnesium oxide is MgO. Count the oxygen atoms on each side.
> The student then wrote: 2Mg + O_2 → 2MgO (the exam would credit 2 of 2)

## Programs that teach it

Each program is taught unit by unit as 15-minute lessons, at five levels from a quick review to the deepest level.

| Program | Curriculum | Units | Topics | Standard (hours) |
| --- | --- | --- | --- | --- |
| AP Chemistry | AP | 9 | 91 | 30.8 |
| IGCSE Chemistry | IGCSE | 12 | 18 | 11.2 |

Every program that teaches chemistry sits beside the others, to one hours scale, on the Programs page.

## What the programs cover

The units of each ready-made chemistry program, as the course itself divides them.

### AP Chemistry

- Atomic Structure and Properties
- Compound Structure and Properties
- Properties of Substances and Mixtures
- Chemical Reactions
- Kinetics
- Thermochemistry
- Equilibrium
- Acids and Bases
- Thermodynamics and Electrochemistry

### IGCSE Chemistry

- States of matter
- Atoms, elements and compounds
- Stoichiometry
- Electrochemistry
- Chemical energetics
- Chemical reactions
- Acids, bases and salts
- The Periodic Table
- Metals
- Chemistry of the environment
- Organic chemistry
- Experimental techniques and chemical analysis

Planned: A Level Chemistry. Until a ready-made program exists you can start a class on any of them from your own notes, and see every program, including those coming soon.

## What the tutor watches for

The mistakes below cost marks most often in chemistry. A tutor that knows them can catch them at the step where they happen.

- Changing a formula to balance an equation instead of the number in front of it.
- Giving the mass of one mole as the answer when the question asks for the mass of the amount used.
- Multiplying by the molar mass when moles are found by dividing the mass by it.
- Forgetting the ratio in the equation when moving from one substance to another.
- Writing an answer to the wrong number of significant figures, or with no unit.

## What it costs

You can start on the Free plan: 45 live class minutes a month (about one class of the default length), no card needed. Pro is $15 a month for 6 hours of live class time, and Pro+ is $30 for 15 hours.

| Plan | Price | Live class time a month | Works out to | Note |
| --- | --- | --- | --- | --- |
| Free | $0 | 45 min | about one class | No card needed |
| Pro | $15 a month | 360 min (6 hours) | $2.50 an hour | $150 a year if paid yearly |
| Pro+ | $30 a month | 900 min (15 hours) | $2 an hour | $300 a year if paid yearly |
| Pico | No monthly fee | Pay as you go | $3 an hour ($0.05 a minute) | Paid from a wallet you top up |

The hourly figure is the plan's price divided by the live class hours it includes, when you use them all. Live class time is the tutor teaching you; other limits (study items, messages, uploads) are on the pricing page.

## Questions

**Can an AI tutor teach chemistry?**

Yes for the concepts and calculations a course asks for. It cannot sit beside you at a lab bench, so practical work needs a teacher or a lab.

**Which chemistry courses does Tutix cover?**

AP Chemistry and IGCSE Chemistry (Core and Extended) are ready-made. A Level Chemistry is planned, and any other course can be taught from your own notes.

**Can it help with stoichiometry and the mole?**

Yes. It is one of the most common places students lose marks, so the tutor takes it step by step.

**Does it check my written explanations?**

Yes. It reads what you write while you are in class and tells you what is missing.
