Finding real help for AP Chemistry when you can't pay for a tutor

AP Chemistry has a reputation, and it's earned. It's a college-level course, it moves fast, and it mixes heavy algebra, abstract ideas, and a lot of vocabulary. If your teenager is struggling, that doesn't mean they're not a science kid. It means the course is hard.

You probably can't teach it, and you don't have to. What you can do is help your teen figure out what kind of stuck they are, then point them at the right help.

Step one: find out which kind of stuck it is

"I don't get chemistry" is too big to fix. It usually breaks down into something smaller:

• Math and units. They understand the idea but lose points converting grams to moles, or rearranging an equation.
• A concept that never clicked. Equilibrium and thermodynamics are common culprits, because everything later builds on them.
• Vocabulary. They can't follow the question because the terms blur together.
• The exam format. They know the material but freeze on free-response questions or run out of time.

Tonight, ask your teen to pick one problem they got wrong recently and talk you through it out loud. You don't need to follow the chemistry. Just ask, "Where did it stop making sense?" The answer is often a single step, and a single step is something you can get help with. (More on that approach in [how to help with homework when you don't know the answer](/blog/how-to-help-with-homework-when-you-dont-know-the-answer).)

Use the teacher, but with a specific question

The cheapest expert in your teen's life is the one who grades their tests. Many students never go to office hours because they don't know what to say.

Help them write a short email or note: "I understand how to set up an ICE table, but I get lost when I have to solve for x. Can I bring problem 14 to office hours Thursday?" A teacher can say yes to that in ten seconds. "I'm lost in chemistry" is much harder to answer.

It can feel awkward for a teen to admit they're behind. It usually goes better than they expect, since most AP teachers like being asked.

Free material built for this exact exam

A few things exist because AP Chemistry is a standardized exam:

• The course outline. College Board publishes a free course and exam description that lists the nine units and what's tested in each. It's a good checklist for spotting gaps.
• Past free-response questions. College Board releases old ones along with the scoring guidelines. Seeing exactly how points are awarded is worth a lot. Often a student loses points for not showing a step, not for not knowing the chemistry.
• AP Classroom. If your teen's teacher uses it, it has practice questions and progress checks. Ask the teacher whether it's set up.
• Free video lessons. Khan Academy has an AP Chemistry course. Videos work best as a way to revisit one confusing idea, not as a replacement for working problems.

The evidence on any one resource being "the best" is thin, and it depends on your kid. Try one for a week. If your teen is working problems and getting somewhere, keep it. If they're just watching, switch.

Practice beats re-reading

The most common AP Chem mistake is re-reading the textbook and feeling prepared. Chemistry is a problem-solving skill, so it gets learned by solving problems, getting some wrong, and fixing exactly why.

A simple routine: a few problems on one topic, then check the answers and write one sentence about each miss ("forgot to convert to kelvin"). Short, regular sessions tend to work better than one marathon; there's more on that in [why five minutes a day often beats one long study session](/blog/why-five-minutes-a-day-often-beats-one-long-study-session).

Other people in the building

• A classmate who's doing well. Two students working through problems together often catch each other's errors. Explaining a step to someone else shows quickly whether you understand it.
• School tutoring or a science club. Some schools offer free peer tutoring, but it's rarely advertised. Ask the counselor.
• A community college or library. Some have tutoring centers or study spaces, and some libraries offer homework help. Availability varies a lot by town, so a phone call is worth it.

An honest note about paid tutoring

A good tutor can help, especially for a kid who's far behind. But it isn't the only path, and plenty of students get through AP Chemistry without one. If paying isn't possible, you haven't failed your child. The list above is a real plan.

Also, sometimes the right answer is a harder conversation: if your teen is overloaded, talk with them and their counselor about whether this course, this year, is the right fit. That's a legitimate choice, not a defeat, and it depends on your kid and their goals.

Where LeftStart fits

If your teen is stuck on a particular type of problem, [LeftStart](/how-it-works) lets them photograph the homework and turns it into practice on that skill until it sticks. It's free, and there's more about [what we offer for high school](/high-school). It won't replace a teacher, and we can't promise a score, but it can make the daily practice part easier to start.

The goal for tonight is small: one problem, one specific question, one next step.
