Build Knowledge

Drill to increase your skill! Wikipedia explains, “The testing effect is the finding that long-term memory is often increased when some of the learning period is devoted to retrieving the to-be-remembered information.” In other words, you remember what you learn better when you answer questions than when you spend the same time watching videos or reading blog posts. Answering open-ended questions (explain a random forest) is generally more effective than answering multiple-choice questions.
