You signed your child up for test prep. Maybe with a tutor, maybe on their own. Either way, you're investing time and money — and you have no idea if it's working.

Lexicor fixes that. Every question your child answers is tracked. You see which skills are improving, which are stuck, and whether practice is actually happening. Not "your child is doing great." Real numbers.

If you have a tutor, they get the same data. They walk into every session knowing exactly what to teach. If you don't, the adaptive engine handles it — picking questions that target your child's weakest areas, adjusting as they improve.

How it works

Set up takes five minutes. Visibility starts immediately.

1

Pick the test

SAT or SHSAT. The platform adapts to the right skills, question types, and scoring for your child's test. More tests coming soon.

2

Your child practices

What makes Lexicor different

Multi-test, one account

SHSAT in 7th grade, SAT in 10th. Switch tests anytime. Your child's progress history stays with them. More tests coming soon.

Adaptive practice

Every question is chosen for a reason. The system finds the skills dragging the score down and builds every session around closing those gaps.

03

Weekly parent reports

Every week you get practice volume, accuracy trends, skill improvements, and where to focus next. Real data, not "they're doing great."

04

Tutor integration

Your tutor gets a dashboard with session prep, targeted drills, and before/after mastery snapshots. They walk in prepared. You see whether sessions are working.

05

PDF worksheet upload

Tutors drop a PDF, AI extracts questions, students do homework digitally. Results flow to the tutor and parent dashboards automatically.

06

Self-serve after tutoring

When the course ends, your child keeps practicing on their own. Same platform, same progress, no tutor required. Your investment keeps compounding.

Frequently asked questions

What tests does Lexicor support?
SAT and SHSAT today, with ISEE and ACT coming soon. Your child picks their test type on sign-up and the platform adapts: the right skills, question types, and scoring for that specific exam. You can switch tests anytime.
How is this different from Khan Academy or other free tools?
Khan Academy is great for learning concepts. Lexicor is built for test prep with full parent visibility. You get weekly reports, skill-by-skill tracking, and tutor integration. We track what matters for the specific test your child is taking, not generic math or reading skills.
What do parents see?
A weekly email report with practice volume, accuracy, skill-by-skill mastery, and what improved or declined. Plus a live dashboard you can check anytime. If your child has a tutor, you see the same data they do.
Does this replace a tutor?
It works both ways. With a tutor, Lexicor makes them dramatically more effective — they walk into every session knowing exactly what to teach. Without a tutor, the adaptive practice handles skill targeting on its own. Many families start with a tutor and continue self-serve after the course ends.
My child's tutor uses Lexicor. What does that mean for me?
Your tutor assigns homework through Lexicor. Your child completes it on the platform. You see results automatically — per-worksheet accuracy, skill progress, and activity. No setup needed on your end beyond creating a free account when invited.
Can my child switch tests later?
Yes. SHSAT prep in 7th grade, SAT in 10th — same account, same parent dashboard. Their progress history stays with them. As we add more tests, they'll be available in the same account.
How much does it cost?
Free to start. Paid plans are available after you see how the platform works. If your child's tutor uses Lexicor, the parent dashboard is free — the tutor handles the subscription. Email hello@lexicor.ai for details.
I'm a tutor. How do I get started?
Sign up as a tutor, create a class, and invite your students. Upload your own worksheets or use the adaptive question bank. Your first 5 students are free. Learn more on the tutor page →
