What Is PastpaperLM?
A one-minute overview of what PastpaperLM does and how this guide is organized.
PastpaperLM is an A/L exam-preparation platform built for Sri Lankan students. It combines real past papers, AI-powered practice, and personalized study tools in one place.
What You Get
Exam Center
Sit full past-paper exams under timed conditions with anti-cheat monitoring, then review every question with explanations.
Module Tests
Practice specific topics, like 'Physics — Mechanics', with no timer pressure — just focused practice.
Epis AI Chat
Your personal AI tutor. Ask questions in Sinhala or English, upload files, and get follow-up explanations.
Backpack
Your personal library: saved results, chat history, uploaded files, bookmarked snippets, and your wallet.
Marketplace
Unlock past papers outside the free year window, subscribe to a plan, or top up credits.
Credits & Billing
A credit-based system — the Free tier gets daily credits, and paid plans add higher caps and better models.
How This Guide Works
The sidebar follows a "start to mastery" order — each section has an overview page plus focused topic pages.
Get Started — account, the one-device rule, your profile, and a dashboard tour.
Sitting Exams and Practicing with Modules — the two ways to practice, end-to-end.
Epis AI Chat and Epis Personalization — your AI tutor, and how to shape its personality and depth.
Backpack, Marketplace, and Credits & Billing — where your stuff lives, and how unlocking and payments work.
Account & Settings and Troubleshooting — managing your profile, and quick answers when something goes wrong.
Use the search bar at the top anytime you just need a quick answer.
Recommended Reading Order
If you're brand new, go through these five pages first — about 10 minutes, start to finish:
The One-Device Rule — read this early to avoid login blocks.
Then jump to whatever feature you need — Sitting Exams, Modules, or Epis Chat.
