## What is Maths Retriever?

Maths Retriever marks your handwriting in red ink, on your own working.

Write the answer on the page with the Pencil. Tap Check. Ticks where you earned the marks, crosses where you lost them, and a note on the line that went wrong.

ALL FOUR IB MATHS COURSES
AA SL, AA HL, AI SL, AI HL. Pick yours once and everything follows: questions, calculator rules, grade boundaries.

WHAT YOU GET
- Exam-style questions, marked the way the exam marks.
- Practise by topic, or one random question when you've got ten minutes.
- Hints that get more specific each time and never give the answer away.
- A mark scheme for every question. Tap Why? on any line.
- Timed mock exams, marked the same way.
- A diagnostic test with a grade out of 7 and a topic breakdown.
- A daily plan that goes after your weak sub-topics.
- A review deck that brings back what's fading.
- A predicted grade that grows with every mark, shown as a range.
- A mistake log that files each lost mark by what went wrong.

FREE AND PRO
Free: Foundation questions in every topic, answers with the key working, 5 marked checks and 10 hints a day.
Pro: Standard and Exam-style questions, mocks and diagnostics, unlimited marking, full mark schemes, per-topic grades, the mistake log.

PRIVATE
No account, no sign-up. Your work stays on your device unless you send a page for marking.

Made for iPad and Apple Pencil. Works on iPhone with your finger.
