When it comes to studying for an upcoming assignment, it can be tempting to over or under prepare. But, when should you study and how much time should you spend on it? Well, for most people, it doesn’t take much time at all. The human brain can only absorb information about a topic for a short period of time each day. In most cases that’s about fifteen minutes. If you spend a little window of time studying each day, it might help you absorb information without becoming overwhelmed.
