Feeling some anxiety is normal as your body releases adrenaline in times of stress which actually triggers your "fight-or-flight" response.

So here are some scientific tips to help you beat that exam anxiety.

Exam anxiety is epidemic among students worldwide.

One study found that out of 1300 people questioned, 96% say that they've experienced exam anxiety at some point in their lives.

And this is a problem because another study found that students who were deemed "highly anxious" perform 12% worse on the exam than those who were slightly anxious or not anxious at all.

Exam anxiety, like all anxiety, is a spectrum, meaning that there's all sorts of symptoms in varying levels of feelings.

Some people may just feel their heart beating a little bit, while others are completely debilitated with nausea and vomiting before every exam.

Getting at least six hours of sleep is crucial before an exam.

Making sure you're well rested will give you the confidence to face the challenge at hand.

Pulling an all-nighter is a huge no no when it comes to your brain having the ability to succeed.

Mitch, did you see Nikki slaying Miley.... Are... are you gonna sleep?

I need a solid six hours before my exam!

Studies have actually shown that those who has a balanced diet up to one week before an exam actually performed better than those who have a high meat or high protein diet.

I have seriously been studying so much. It's like eat, sleep like Hollison.

Hey, here's your lunch by the way.

Ohhh, thanks!

What's glucose?

In fact, it's best to have a breakfast that's high in fiber and high in carbohydrates, so that the energy is released slowly and your brain doesn't crash in the exam.

Losing energy quickly means losing your concentration, which means you might start to panic when you can't even answer the easy questions.

Name.

What's my name?

Oh, god, what's the date?

Positive self-imagery has been known to boost confidence and lower exam anxiety.

But, it only works if you set yourself realistic goals.

I will get at least an 80% on this exam.

I will not fart during the test.

And I will have a banana for lunch.

Now, we're not telling you to lower your expectations, but it is not mentally healthy to expect a 100% on all of your exams.

So, while feeling confident for an exam is important, it's essential that you keep your feet planted on the ground.

To help destress, trying picture yourself in a happy moment, whatever that might be, and then quickly switch to imagining yourself in the exam room.

I'm on a boat with whales around me.

Humpbacks. Fin whales!

Hectors, even a blue whale!

One comes up to me and lets me pat it, and he playfully splashes me and winks.

He loves me and I'm one with him.

Also, glycine, alanine, valine, leucine are all nonpolar assets and this is how you drop them in an exam.

This helps your brain to associate those happy feelings with writing the exam and primes you to be ready.

In addition, before the exam, trying picture questions that you've already studied the answers to so that will boost your confidence going in.

Speaking of priming, it's important that you familiarize yourself with the exam room.

If the exam room isn't your classroom, make sure you take a short field trip there few days before. This will also ensure you aren't late.

By seeing the setting beforehand, it will help your brain be at ease during the exam, help you feel more confident and perform better.

Well, hopefully, you have a good circle of friends and study buddies you can work with.

There's always that one Debbie Downer on the group that kind of lowers your self-confidence.

This combine with your past experience on the exams which might not have always been good, can low your self-confidence moving into the exam.

A helpful trick is to write down these insecurities on a piece of paper, and then right below them write down a rebuttal which makes you feel confident, then crumpled that paper and throw it away.

People say I have a bad memory, but I have never forgotten somebody's birthday.

This can help you build confidence before a test, and these symbolic gestures are actually effective.

One study found that anxious students who wrote down their worries before a test did better than those who didn't.

Hopefully these scientific tips will help you go into your exam with confidence and feel like much less anxious.
