Daily quant quiz and practice
Practise for the Tahsili science test for free: physics, chemistry, biology and maths. After every question you see why you got it wrong, and the mistake stays with you until you fix it. No sign-up.
HOW IT WORKS
• Short sessions of 5 original questions, 4 options each.
• No timer in practice.
• A hint shows the method, not the answer.
• "Not sure? Show me" instead of guessing.
AFTER EVERY ANSWER
• Why the right answer is right.
• Why the wrong option tempted you ("You chose B: …").
• The full step-by-step solution, free 3 times a day. It opens by itself after a wrong answer while today's 3 last.
• The science term in Arabic and English.
MY MISTAKES
Every mistake is saved and comes back at spaced intervals until you answer it right twice, on two different days. One review session a day is free. No mistake gets lost.
MY READINESS
A percentage per subject from your accuracy and the units you've covered, with the number of questions behind it, so you see your weakest subject. No predicted scores.
DARE A FRIEND WITH THE SAME QUESTIONS
After a session, share a picture of your result, like "4 / 5", with a link. Your friend plays the same 5 questions and sees both results: "You 3 · Noor 4". No account needed, nicknames only.
ARABIC AND ENGLISH, TEXTBOOK SYMBOLS
Everything in both languages; switch any time with "ع | EN". The English version uses standard notation and SI units; the Arabic version reads right to left with Arabic symbols and units, as in the Arabic textbook.
QUICK PRACTICE
Optional: 60 seconds per question to practise speed.
Practice works offline. Purchases, restoring and signing in need a connection.
1,456 original questions: physics 382, chemistry 357, biology 376, maths 341, in 42 units named after the Saudi textbook chapters. We care less about how many you answer than about how many mistakes you fix.
