Not just right or wrong
It finds where your child is losing points
- Knowledge is not yet solid
- The wrong approach was chosen
- Can do it, but not yet accurately
- Taking too long
- Falling into the same trap again
Then TUXA plans what to practise next around the exam and that child's real data.

FAQ
Frequently asked questions
Which exams does TUXA cover?
Open exam tracks: the grade-7 entrance exam for the Princess Chulabhorn Science High Schools, grade-7 special programmes in the SMTE, Gifted, AP and Palang Sib style, and the general grade-7 programme. One track includes both maths and science, and the app counts down to that exam's date.
How is TUXA different from a typical exam app?
TUXA's goal is not to make children do as many questions as possible, but to practise what matters first and repair the places where points are really lost — worth the time that remains. It separates points lost to knowledge, reasoning, accuracy, time, or the same trap again and again.
How much does TUXA cost?
TUXA is sold per exam track, from 599 baht per month for one track (maths and science for that track). Choose 1 to 8 tracks. The exact price and entitlements are shown for you to check before you confirm.
What does the free trial include?
Sign up in the app for a 7-day free trial, which includes one subject, one practice set, one mock exam and three days of missions.
Is TUXA safe for children?
No ads, no chat with strangers or social features, no endless feed, no in-app purchases by children, account and data deletion in the app, and children's data handled under Thailand's PDPA.
Which devices does TUXA run on?
It is available on both the App Store and Google Play. An internet connection is needed while practising, because every question comes from the server. All content is in Thai.
