Why choose TERA?

What we stand for

A student reading printed study material

Practice stays complete

Question-paper pages keep their original working space and readable scale.

Waste is made visible

Every compilation reports its source pages, output pages, and calculated reduction.

Claims stay honest

No universal trees-or-water figure is invented from a page count. Assumptions remain visible.

Access stays simple

No account is required. Local PDFs are processed in the browser whenever possible.

Transparent impact

We show the calculation, not a marketing fantasy.

TERA can measure the printable pages it removes. The calculator converts a real scenario into sheets and paper mass, while separating those estimates from wider life-cycle impacts.

Read the methodology

This is a planning scenario, not verified real-world savings. Wider environmental effects depend on paper type, recycled content, mill, energy mix, and transport.

The paper problem

Keep the learning. Remove what adds nothing.

Paper remains essential in many classrooms. TERA does not shrink the student’s working space or remove questions. It targets genuinely blank pages, mark-scheme covers, and generic guidance, then packs the actual answers clearly.

Past-paper booklet maker for Cambridge qualifications

TERA currently supports verified Cambridge International catalog selections and your own permitted PDFs for AS & A Level, O Level, and IGCSE practice. Students can build and download a free past-paper booklet PDF after reviewing the generated question-paper and compressed mark-scheme pages.

Pearson Edexcel, AQA, OCR, IB, and other international boards are on the validation roadmap. They are not shown as live sources until their catalogs, document patterns, and usage conditions have been verified.
