On-Screen Marking System

On-screen marking is a digital evaluation method where evaluators assess scanned answer scripts on a computer screen instead of marking physical paper booklets. MAPLES OSM provides a purpose-built evaluation interface with annotation tools, question-by-question navigation, and automatic score validation — enabling faster, more accurate, and fully auditable evaluation.

The Evaluation Interface

The evaluation screen uses a 3-panel layout designed for uninterrupted marking. Everything an evaluator needs is visible at once — no switching tabs, no scrolling through menus, no lost context.

Reference Materials

Answer key, marking scheme, and question paper displayed side-by-side for quick reference during evaluation.

Answer Sheet Viewer

High-resolution scanned pages with zoom, pan, and brightness controls. Navigate between pages seamlessly.

Question Grid

Color-coded grid showing progress — green for marked, yellow for flagged, grey for pending. Jump to any question instantly.

Marking & Annotation Tools

Tick & Cross Marks

Single-tap tick or cross annotations placed directly on answer scripts for fast marking.

Freehand Drawing

Draw circles, underlines, or custom annotations on the answer sheet with pressure-sensitive freehand tool.

Undo & Redo

Unlimited undo/redo for annotations — every stroke is reversible with full history.

Score Validation

Every mark entered goes through automatic validation before the evaluator can submit. This eliminates the totalling errors and missed questions that are common in manual evaluation.

  • Auto-calculates total marks across all questions — eliminates manual totalling errors
  • Flags unattempted questions so evaluators can explicitly mark them as not attempted
  • Validates individual question marks against maximum marks — prevents over-marking
  • Sub-question score verification ensures part marks add up to question total
  • Warns evaluators before submission if any question remains unevaluated

Built for Evaluators

Keyboard Shortcuts

Number keys for marks, arrow keys for navigation, Enter to submit. Power users evaluate 3x faster without touching the mouse.

Auto-Save

Every annotation and mark is saved in real-time. Network interruptions, browser crashes, power cuts — nothing is lost.

Multi-Language Support

Interface available in English, Hindi, and Tamil. Evaluators work in the language they are most comfortable with.

Dark Mode

Dedicated dark mode for evaluators working long sessions. Reduces eye strain across multi-hour evaluation camps.

3-Panel Layout

Reference materials, answer sheet, and question grid visible simultaneously — no tab switching, no context loss.

Instant Page Load

Pre-fetches next pages in the background. Evaluators never wait for images to load between pages.
