Help & FAQ

High school chemistry students and their teachers. Students practice lessons, earn XP and ranks, and can ask Chem Coach for help. Teachers see how each student and the whole class is doing.

Go to Manage → Classes and create a class. Each class has a join code. Share that code with your students; they tap Join a Class on their home screen and enter it.

As many as you like: classes and students are unlimited on every plan. Each month the free plan includes 6 assigned lessons, 3 live games, 1 Save the Reactor week, 2 tests and 3 reteach lessons. Teacher+ removes the monthly limits.

Yes. Open the class from Manage → Classes and use the archive button. Archived classes are listed separately and can be restored.

Yes. Sign in at app.chemcoach.ai in any modern browser. On a laptop or landscape iPad, teachers get a desktop layout with a sidebar and a sortable Students table.

Each student gets one status, based on the most important thing going on:

• Red (needs help): one or more assignments past due and not started, no activity for 14 days or more, or very low scores across several assignments.
• Yellow (watch): an assignment turned in late, no activity for 7–13 days, low scores, or one weak skill.
• Green (on track): none of the above.

The text next to the light always names the specific reason, like “Missing 2 Assignments.”

Each assignment is scored out of 5. 5/5 is Mastered, 4/5 is Complete, and anything lower is In progress. Students can keep practicing to raise their score.

On the Teach page, it shows your class’s accuracy on each high school physical science standard (HS-PS). It pools every question tagged to that standard, counting each student’s most recent try. A dash means your class hasn’t answered questions for that standard yet.

Your list of skills to go over again. The Class Skill Check on your Overview shows how accurate your class is on each skill and recommends which to reteach; use the ⋮ menu on a skill and choose Add to Reteach Plan. On the Teach page, add a note, then mark each skill Retaught once you’ve covered it, or Dismiss it.

Open Students and click or tap a student. You’ll see their assignments, strengths, weak spots, and recent activity. Tap an assignment to see each attempt.

Go to Manage → Create an assignment, pick a lesson, one or more classes, and a due date. Students see it on their home screen, and you can follow progress on your Overview and in the assignment calendar.

Yes. Open the student from Students and use Excuse in their assignments list. An excused assignment no longer counts as missing, and you can restore it later.

Students can still complete it; it’s marked late. Students who haven’t started it show as missing until they do, or until you excuse them.

Students can report a question from the quiz screen; the report goes to their teacher. Teachers see reports under Question flags, where you can look at the question and either dismiss the report or send it on to us. Teachers can’t edit questions directly; every question is reviewed centrally, so a fix reaches every class.

No monthly limits on assigned lessons, live games, Save the Reactor weeks, tests or reteach lessons, plus mastery for every NGSS standard and skill. Every feature is in the free plan too; Teacher+ is for teachers who use it every week.

You earn XP by practicing, and XP moves you up through the ranks. Your streak counts how many days in a row you’ve practiced.

A Boss Battle is a challenge for one topic: answer correctly to push the reactor pressure back and win. Meltdown is the endless mode: see how long you can keep the reactor stable.

Ask Chem Coach about any chemistry question and it will explain, quiz you, or point you to a lesson. You get 10 free replies every week; the count resets each Sunday. For more, Chem Coach+ is $4.99/month for unlimited replies, or you can buy credit packs that never expire. Chem Coach can make mistakes, so check anything important with your teacher.

Your name, your progress and scores on lessons and assignments in their class, and when you were last active.

Yes. Chem Coach is an AI tutor. Its explanations are written by a large language model from a third-party AI provider, guided by the student’s question and our chemistry lessons. When a quiz matches a lesson, its questions come from the same question bank as that lesson. Messages and the question context needed to answer them are sent to the provider to write each reply; we don’t sell that data or use it to train third-party AI models. Chem Coach won’t hand over answers to pasted homework problems — it walks students through the method instead — and if a student asks whether it’s a person, it tells them it’s an AI. It can make mistakes, so students should check anything important against their lesson or with their teacher. See the Privacy Policy for details.
