Revising differently by subject: the comparison

A big mistake is revising every subject the same way. Reciting a history course by heart won't help in maths, and redoing exercises won't be enough in languages. Each type of subject has its own learning logic.

Subjects to practise

For maths, physics or anything that requires solving, the key is doing, redoing, and redoing exercises again. Understanding the theory isn't enough: it's active repetition that builds the reflex. Focus on the exercises you got wrong.

Subjects to understand and connect

For history, geography or descriptive sciences, don't recite blindly: look for links, causes and consequences. Build diagrams, timelines, mind maps. Info connected to other info is remembered far better than isolated info.

For languages, nothing replaces regular use: reading, listening, speaking a little every day. A language course is lived more than it's revised. Match your effort to the nature of the subject and you save loads of time.
