The old-school method of algebra practice was 'drill and kill' - doing hundreds of mindless, repetitive problems.

While practice is essential, mindless repetition is an incredibly inefficient way to learn.

This is the fallacy: The goal of practice is not to get answers right. The goal is to understand the process.

Intelligent practice focuses on variety, not just volume. You should be doing different *types* of problems.

It involves 'interleaving' - mixing up different types of problems rather than doing one worksheet at a time.

This forces your brain to identify the right strategy for each problem, which is a much deeper skill.

Intelligent practice also involves deep analysis of your mistakes. Why did you get it wrong? What's the lesson?

Simply doing another problem without understanding your last error is a waste of time.

Quality over quantity. 10 problems done with focus and analysis are better than 50 done mindlessly.

Don't just 'drill and kill.' Practice with purpose, variety, and a focus on your errors. That is the path to mastery.
