How Quelpr works

  1. 1

    Pick your subjects

    Choose the CSEC or CAPE subjects you are sitting. Quelpr builds a concept map of every topic in the syllabus.

  2. 2

    Drill the weak spots

    Answer real past-paper questions. Quelpr tracks which topics you have mastered and keeps sending you back to the ones you have not.

  3. 3

    Get marked like an examiner

    Every answer is marked against the question's own mark scheme, point by point — including diagrams, graphs and Punnett squares.

Questions students ask

Which exams does Quelpr cover?

Quelpr covers CSEC and CAPE (CXC) subjects, with over 10,000 questions taken from real past papers — Mathematics, Additional Mathematics, Physics, Chemistry and Biology at CSEC, and Pure Mathematics, Physics, Chemistry and Biology at CAPE, across both units.

Does Quelpr work offline?

Yes. Open a subject once while you have data and its questions and diagrams are saved to your device, so you can keep practising with no connection. Anything you answer offline syncs automatically the next time you come online.

Can I put Quelpr on my home screen?

Yes. Quelpr installs like an app straight from your browser — on iPhone tap Share then Add to Home Screen, and on Android choose Install app from the browser menu. There is nothing to download from an app store.

How are my answers marked?

Each question carries the mark scheme from its past paper, and your answer is marked against it criterion by criterion, with a reason for every mark. Written answers, calculations, drawings, labelled diagrams and plotted graphs are all marked.

Can I answer questions that ask me to draw or plot something?

Yes. Drawing questions give you a canvas, questions that ask you to label a figure let you write straight onto the paper's own diagram, graph questions give you a plotting grid with the axes already set up, and Punnett square questions give you a grid to fill in.

What devices do I need?

Any phone, tablet or computer with a web browser. Quelpr is designed mobile-first, so a phone is enough.
