<p>Completely and utterly disagree on points 1-3. Here is why.</p>
<ol>
<li><p>Caffeine can make you jittery and nervous, particularly if you don’t normally have it. Never try anything new on test day. I don’t ever have caffeine and I have no trouble keeping my stamina up for long tests. Why? Because I eat well. Which brings me to the next point.</p></li>
<li><p>Just like with caffeine, you can’t make a blanket statement that if you eat a good breakfast, you won’t need snacks. For one thing, if you eat too much at breakfast, it can make you physically and mentally sluggish. But the added stress of the test can more quickly deplete energy, and a mid-test snack is a good way to perk back up without running the risk that you make things worse by sucking down caffeine and sugar. I personally eat an apple followed by a granola bar that has nuts or peanut butter. A small snack with a combo of protein, natural sugars, fat and complex carbs works great. It gives you a complete boost, and you won’t crash later on.</p></li>
<li><p>Monsters and Red Bulls work for some people, but I have read many more horror stories about drinking them on test day than good ones. Eat a proper snack and you won’t need one.</p></li>
</ol>
<p>You other advice is pretty good, but your advice to take in a lot of caffeine and crap like Red Bull, not so much!</p>
<p>For the record, I am hypoglycemic and have had to learn a lot more about nutrition than I ever wanted to, but I can personally assure you that you’re less likely to crash and more likely to keep your mental and physical energy up if you use good foods, not caffeine and energy drinks.</p>
<p>Whatever you try, try it out while you’re doing practice tests, not on test day!</p>
