HRT or no, sleep is important, especially when you're studying. Sleep is when the brain solidifies what it's learned that day, so getting a good night's sleep before an exam is especially important. And study after study has shown you can't function properly without getting proper rest. Is it just studying that's keeping you up, or are there, um, extra-curriculars you could cut back on? I think you're driving yourself too hard. Slow down! Get some rest! (says Mama-bear...)
