I'm in school too..and I was planning on getting some individual braids like kinky twists or nubian twists (my head is too big for cornrows or frenchbraids... lol)... and i have also considered a full sew-in in the winter...

I'm doing it so I won't have to worry about my hair during school and also to give my hair a break from all the constant styling that I do... in my opinion my hair grows a little longer at a faster pace when I have braids. And I prefer kinky twist or something of that nature because it's a less chance of it pulling your hair out ( ex. micros) depending on the type of hair you use you can probably try senegalese ...

when it comes to getting braids for school and protective styling... I say go for it! it'll be good for your hair and good for you at this time in your life..
