Inside every lesson
You always know where you are: read the rule, watch it worked, learn the traps, then practice. Finish a lesson and its square on your map fills in.
What the skill is, when the test uses it, and the one idea that makes it click.
SAT-style questions solved step by step, with the reason each wrong answer is tempting.
The mistakes students actually make on this skill, and how to spot them before you do.
Exam-style questions with full answers, plus Desmos checks you can run beside the lesson.

From the free lesson on percent change. Each worked example shows the steps, why the other answers are wrong, and a Desmos check you can run.
Worked example · Percentages
A store's monthly revenue was $4,000 in January. In February, revenue increased by 15% from January's amount. In March, revenue decreased by 10% from February's amount. What was the store's revenue in March?
How the lesson solves it
Why the other answers are wrong
Desmos check
Type 4000 * 1.15 * 0.90 and Desmos returns 4140.
Successive percent changes multiply: 1.15 × 0.90, never 15% − 10%.

Nova is Novark's AI tutor. Open it from any lesson and talk it through out loud or in chat. It asks questions that lead you to the step you missed, so the idea is yours when the test comes.
Why isn't it just 15% minus 10%, so 5% up?
Good question. The 10% comes off February's revenue, not January's. What was February's revenue?
$4,600. So 10% of that is $460…
Right, which leaves $4,140. Changes in a row multiply: 1.15 × 0.90 = 1.035, a 3.5% rise overall.
