Sleeping Late Before the SAT

<p>Hello CC,</p>

<p>Are there any major disadvantages to sleeping late before a big exam like the SAT?
I know if I decide to sleep late, I could be risking concentration. Is it possible though to concentrate without enough sleep? I would probably eat a good breakfast and I usually don't panic. What are your thoughts? Has anyone been in a situation like this before? Did you sleep little but still managed to concentrate? Please give me tips....</p>

<p>Thanks in Advance :)</p>

<p>I wonder the same thing.</p>

<p>I’ve tried it before and it was not a good idea at all I messed up the whole exam especially the CR sections I suffered during the exam from a severe headache and yawned too much that I couldn’t concentrate so you better get enough sleep</p>

<p>Oh I should better get enough sleep then. The only thing is that I’m not done studying…
I’m lost really.</p>
