How it's used
Focuses on the urgency and intensity of the learning process, often implying that the person is behind schedule or facing an immediate deadline. It carries a sense of desperation or last minute effort, distinguishing it from regular studying or reviewing. It is frequently used in academic or professional contexts where a specific skill or knowledge gap must be bridged quickly.
Examples
You haven't even practiced the basics, so no amount of cramming will help.
Related words
Common mistake
Do not use this to describe long term or steady learning, as it specifically implies a short, intense burst of effort to catch up. It is not a synonym for general revision like 溫書.
