<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>
