Is it worth staying up all night studying for a coming midterm you feel ready or is better to get good sleep?

It's almost always better to get good sleep than to stay up all night studying if you already feel ready for the midterm. Pulling an all-nighter will likely impair your cognitive functions: memory recall, critical thinking, and problem-solving will all suffer. This means you'll likely perform *worse* on the exam than if you were well-rested.

The time you spend studying while sleep-deprived will likely be less effective than a few hours of focused study followed by a good night's sleep. Your brain needs rest to consolidate information and make it readily accessible.

If you feel ready, trust your preparation and prioritize sleep. You'll perform better and feel better in the long run.
