Pestle

Pestle+ enables you to level up your revision by revising for Math SL and HL at an appropriate difficulty, always allowing you to challenge yourself and refine your skills.

Pestle+ does this by organizing all Math questions by difficulty, which has been identified using a hybrid algorithm that uses Natural Language Processing techniques to analyze IB examiner remarks and combines it with information about the question length and position in the paper.

You can also challenge yourself with our Timer, that calculates how much time you would have to complete a question during your final IB exams, and allows you to attempt it at varying fractions and multiples (25%, 50%, 75%, 100%, 125%, 150%, 200%) as per your own needs.

Each question also leads you to 10 other Related Questions, which have been identified using subject-specific tags and Natural Language Processing. These questions, tagged by difficulty, allow you to achieve mastery of a sub-topic at your own level and pace.

UPDATE: Now supports Related Questions for Chemistry, Physics, and Biology!
