that save time.

When a question gives you a list of scores, enter the values once. Desmos can calculate their average for you—no adding and dividing by hand.

List it. Then ask for the mean.

L = [12, 17, 19, 24, 27, 31, 34, 40]mean(L) = 25.5

For raw data, type mean(L) in Desmos. It updates instantly if you change the list.

01 / FOCUSED PRACTICE

Practice for the exam you’re taking.

Choose your exam, then work through a focused session. SAT practice uses adaptive modules; other exams keep their own section structure.

More than a bank
of right answers.

Learn, practice, and get unstuck in one place. Each step has a destination—so a missed question doesn’t leave you searching for what to do next.

Build the skill first.

Worked lessons connect directly to exercises on the same topic. No detour into an unrelated test.

Explore lessons

A challenge that fits.

Every SAT lesson topic has Foundations, Standard, and Challenge exercises. Move up when you’re ready; revisit the basics when you need them.

Before you start.

What happens after I miss a question?

Review the explanation and your skill breakdown. Completed practice can add relevant course lessons to Suggested, where you can see which session they came from. Open a lesson, then use Practice this topic to stay with that skill.

Are these official exam questions or scores?

Zenith is independent of exam providers. Its practice material is independently authored, and some quantitative exercises use number variants. Practice results are learning feedback, not official scores or admissions predictions.

Does every exam use SAT-style adaptive modules?

No. SAT full tests use adaptive second modules. Other courses use their own test structure and permitted tools. Check the exam and section details before beginning.

What can I use for free?

Start with free practice and a seven-day Pro preview. Your account shows the access available for your selected course and when a preview expires. When it ends, your account returns to Free unless another access grant applies.

Can I keep studying the same skill?

Yes. Use Learn and Practice this topic instead of starting an unrelated full test. Save useful methods in Shortcuts, and return to Suggested for lessons linked to your completed work.
