What makes Mathnova better

It starts with reading your actual scratch work, not just your answers.

Scratch work · the why

We tell you why you got it wrong, not just what.

We read your actual handwritten scratch work to tell you why you're getting a question wrong: whether your logic is breaking down at the setup, in formula recall, or in a calculation slip.

Every miss gets classified

Katy's miss here was a formula-recall slip, not a concept gap.
Q29IncorrectGeometry & TrigMedium0m 51s
A guy-wire runs from the top of a tree stump to a stake on the ground, forming a right triangle. The wire is 10 ft long and meets the ground at angle θ. Which expression gives the height of the stump?
A10 cos θ
B10 sin θ
C10 tan θ
D10 / sin θ

Katy, you drew the right picture and identified the right triangle. Then you used cos θ to find the stump height when sin θ was needed, because the stump is opposite the angle, not adjacent. Other diagnostics see "wrong answer in Geometry." Your scratch work shows it's a formula-recall slip, not a concept gap.

Scratch work · the pattern

We find the one habit hiding across different questions.

Wrong answers on unrelated topics often share a single root behavior. We connect them across your whole test, so what looks like four separate gaps turns out to be one habit you can fix at once.

Four misses, four topics — one underlying behavior.

Katy, you missed Q17, Q18, Q21, and Q30. Different topics, different difficulty levels. Other diagnostics report them as four separate gaps. We found one underlying behavior: you answered with an intermediate result, not the one asked.

Q17 (PSDA)P(B|A) instead of P(A|B)
Q18 (Adv Math)Linear instead of exponential
Q21 (PSDA)Upper-bound vs full interval
Q30 (Geometry)Radius instead of diameter

Scratch work · the better way

We see the approach you took, then show you a faster one.

Because we read your scratch work, we know the exact method you used, not just your answer. So we can advise the best approach for next time and help you win back time on the clock.

Same right answer, far less time, because we know the method you used.
Q10CorrectAlgebraMedium2m 8s
What is the greatest integer value of x that does NOT satisfy the inequality x+32x−14 ≥ 3?
A3
B4
C5
D6

Katy, you plugged each answer choice into the inequality until one worked. It got you to the right answer (4), but it ate the clock. Because we saw your approach, we can show you a faster path.

Tested each answer choice one by oneYour approach
Clear the fractions and it collapses to x ≥ 5, so the greatest non-solution is 41 step
Type the inequality into Desmos as written and it shades x ≥ 5 on the spotInstant

Targeted practice

My favorite feature of Mathnova is how it analyzes the problems you got wrong on a diagnostics test and finds the topics you need the most help with, and using that information, it then gives you additional practice in those areas instead of making you waste time on concepts you already know.
