Cognitive enhancers can change how people remember things and learn. But remember, the results aren’t always huge. Here’s what I’ve noticed:

• Nootropics, like caffeine, can give you a quick energy boost.
• Prescription drugs can help you focus, but they can also have risks.
• Natural supplements seem to work, but scientists are still studying them.

So, while these things might help you a little, they can’t take the place of good old-fashioned studying!
