All of us have been there. We've all been there. You're actually doing your body a disservice. To fully function the next day, your brain needs to get at least 7-8 hours sleep each night. Our concentration and energy levels should be high. This can only happen when we get the sleep our bodies need. This is probably what you are thinking as you sit there reading it. Listen to what we have and don't say anything!
Even though you might not be sleeping enough, naps can help you get through the day. To keep your brain active, take only a 30-minute snooze. Studies show that naps and short study periods can make you more energetic when you return from your studies.
You can set a study plan before you begin exams to give yourself a time to fall asleep and when you should wake up. It is important to set a time frame between when you go to sleep and when you wake up. It may take some time for your body to transition into sleep. The same applies to waking up. Nobody wants to get out of bed as soon as their alarm goes off.
The bottom line
It may seem like you think that studying more material will help you pass the test. I'm sorry to burst your bubble but this is not going to be the case. You may crash during the test if you don't get enough sleep. This is something we don't want to happen, so ensure you are consistent with your sleeping patterns.
