How to use this tool

• Select an exam centre: the sidebar sets the correct time limit, backspace rule, and passage set for that exam automatically.
• Set your time: use the dropdown to override the default duration, from 1 to 30 minutes.
• Start typing: match the passage exactly. Green means correct, red means incorrect, and the gold block marks your cursor.
• Backspace-locked modes mirror SSC and High Court exam rules: once a character is typed, it cannot be deleted, so accuracy matters more than speed of correction.
