About us

StudyDex (previously MT Academy) is founded by Henry Lin. Henry holds a PhD in Biotechnology from the University of Cambridge, an MSc in Biochemical Engineering from University College London and a BSc in Medical Biochemistry from King’s College London. He began tutoring Maths and Sciences for both GCSEs and A-Levels in 2012 and is currently one of the top rated tutors in South East London. He created this website with the initial goal of providing a catalogue of past papers to A-Level Maths students, but has since expanded to GCSE as well as Biology and Chemistry. In addition, the website allows students to track their progress according to the specific requirements of their specifications.


StudyDex provides a vast catalogue of past papers neatly organised by syllabus and subject. In addition to the current syllabuses, archives of past papers from previous syllabuses are also available for students to prepare for their exams.

My Maths Tracker

My Maths Tracker is a unique and interative system where students can track their progress tailored to their particular specification. The specification links to topics where students can study and practise questions for free.
