A partner that plans with you and personalizes the practice.
Tell Practimetra's AI assistant what you know about the learner, in your own words. It combines that with their diagnostic and the standards for their test to draft a plan, reworks it whenever you ask, and writes practice shaped to their needs and interests. Nothing changes until you accept it.
Free during the pilot. For families, and for students 13 and up who plan their own prep.

EXAMPLES
Maya's math test is in 8 weeks. Where should we start?
Going by her starting map, I'd start with dividing fractions, then ratios, then integers, with a progress check after each. That's 18 sessions of 20 minutes.

THE PROBLEM
Practice without a diagnosis is just guessing, with homework attached.
Learners repeat the same mistakes because nobody finds out why they happen. Confidence drops before the test does.
Parents see a percent correct, not which skills are weak or whether they're getting stronger. So they nag, or they pay for a tutor.
Everyone gets the same set. Worksheets and question banks hand every learner the same questions, whatever they already know, need or care about.
WHAT WORKS
Find the skills that are actually weak, then practice built for one learner, not a standard set: their weak skills, at their level, in wording that suits them, themed around what they love. That's what Practimetra does.
How it works
You talk. They practice, on questions made for them.
01
Tell the assistant about the test
Which test, when it is, what your learner has covered in class, how long they can focus. Plain words are fine.
"The test is in May. Algebra is new this year, and he loses steam after about 15 minutes."
02
A short diagnostic draws the starting map
Your learner takes it in parts, on their own device. Every wrong answer choice is tied to a known misconception, so a miss tells you why, not just that. You see every skill on the test as secure, shaky or not yet.

03
The assistant drafts the plan. You approve it.
Weakest skills first, sized to the time left. Ask for changes until it's right; nothing starts until you say so.

04
Questions written for your learner
Tell the assistant what they need and what they love. "Fractions are her weak spot" focuses the set on that topic, at the difficulty you choose. "Word problems trip her up" gets shorter, plainer wording. "She loves soccer" sets it on the pitch. The standard behind each question never changes, and you preview the set before your learner sees it.
Standard question
A machine fills 3 boxes every 5 minutes. How many boxes does it fill in 20 minutes?
For Maya: plain wording, loves soccer
Maya's team scores 3 goals for every 5 corner kicks. At that rate, how many goals from 20 corner kicks?
Same skill: ratios and rates · same standard
05
Practice, then prove it
Short sessions with a worked explanation for every question. A skill counts as solid only after a progress check confirms it, and you see it on the progress page.
Proportional reasoning
Confirmed by progress check
The AI assistant
AI that works for the parent, not around them.
Other apps put a chatbot in front of your learner. We put a planner beside you: it knows the test, listens to you, and follows rules you can read.
Knows the curriculum
Every session maps to the standards on your learner's test.
Plans around real life
What they covered in class, how long they can focus, a test date that moves.
Questions made for your learner
Name a weak topic, say word problems trip them up, or mention what they love. The set is written to the same standards, and you preview it before they see it.
You stay in charge
Nothing changes until you click Accept. In chat, the assistant sees an alias, never your learner's name.

What you tell the assistant, and what changes.
"He covered fractions in class and aced the unit test."
→
Fractions skipped where he was right in the diagnostic. 4 sessions moved to equations.
"The test moved up two weeks."
→
Plan resized to 14 sessions. The two weakest skills keep their time; lighter review elsewhere.
"Fractions are his weak spot, and long word problems lose him. He loves baking."
→
Personalized set: fraction questions in short, plain sentences, set in his kitchen. Same standards; you preview it first.
"Give her 10 quick questions on ratios for tonight."
→
Practice set ready: 10 fresh ratio questions, medium difficulty, about 12 minutes.
Features
Everything test prep needs, in one place.
Built around one idea: find out why a question was missed, then practice that, not the symptom.
Mistake detective
We don't just mark it wrong. We show why.
Every wrong answer choice is tied to a known misconception, so a miss tells you what went wrong, and practice goes to the real problem.
Maya answered
3/4 ÷ 1/2 = 3/8
What it usually means
Multiplying instead of dividing fractions
Dividing fractions: "not yet" on her map
Short sessions that fit a school night
Anywhere from 1 to 40 questions. You choose the session length, and progress saves on any device.
Explanations that teach
Every question gets a worked explanation in the review right after the session ends.
Diagrams, graphs and number lines
Questions look like the real test, with clean math notation and visuals that work on a phone or tablet.
One account for the whole family
Several learners under one parent account. Learners sign in with a code and PIN, no email needed.
Questions that show their receipts
Each question is written to a named standard. Questions from our bank pass automated accuracy checks, and you can preview any set first.

Question 6 of 12Ratios
A recipe uses 3 cups of flour for every 2 cups of milk. How much flour goes with 8 cups of milk?
A. 9 cups
B. 12 cups · correct
C. 11 cups
Why: 8 cups of milk is 4 groups of 2, so you need 4 groups of 3 cups of flour: 12.
Where it works
Any test built on published standards.
Practimetra loads a test's official standards and generates fresh, checked practice for them. We're starting with these, and adding more each season.
NOWState tests · STAAR grade 6 mathCredit by Exam · grades 6–7 math and scienceSAT Math · Algebra, early access
NEXTAP examsMore state testsScience, reading and more
Privacy by design
Your child's data is not the product.
Built for children under 13 from the ground up, under the U.S. children's privacy law (COPPA). We collect only what practice needs, and you stay in control of all of it.
Today: STAAR grade 6 math, Credit by Exam grades 6–7 math and science, and SAT Math (Algebra) in early access. AP exams and more subjects follow. Every question is written to the official standards for the test your learner is taking.
What does the AI assistant do, and what doesn't it do?
It helps you build and adjust the practice plan, and creates practice sets when you describe them, shaped to your learner's weak topics, reading needs and interests. Personalizing changes the story and wording of a question, never the skill or the standard. It doesn't chat with your learner or hand out answers. It suggests; you approve. In chat, the assistant sees an alias instead of your learner's name. Please leave names out of notes for practice sets: we send those notes to our AI provider to write the questions.
How much time does it take each week?
You choose the session length when you set up the plan, and the plan spreads skills across the time left before the test.
Is this a replacement for a tutor?
It's a focused practice partner, not a tutor. Many families use it on its own; others share the starting map with a tutor or teacher so their time goes to the right skills.
Where do the questions come from?
They are original questions written to each standard. Questions from our bank pass automated accuracy checks; personalized sets are written on request, and you can preview any set before your learner sees it. They are not copied from official tests, and we never claim they are.
Can my teenager use it on their own?
Yes. Students 13 and older can create their own account, take the diagnostic and plan their own prep with the assistant. Younger learners need a parent to set up the family account.
What do you do with my child's information?
We use it only to run practice for your learner. We don't show ads or sell data. You give consent before we collect anything, and you can download or delete it at any time from your account.
