I'd say that it depends on the cologne... And don't go too heavy on it.
When you enter the wonderful world of male fragrances, you tend to never get out. I used to be okay with one bottle (Tommy by Tommy Hilfiger) but then I discovered that there was so many others and I've bought 6 new colognes over the past 6 months, each one for special occasions.
When you go to school, don't wear something too heavy like Le Male by Jean-Paul Gaultier, try something more like Acqua di Gio by Armani or Blue Jeans by Versace.
This stuff's pretty complicated, but start off with Acqua di Gio or Blue Jeans for school. Those are the ones I use.
For other occasions, there's other colognes. If interested in my opinion, just ask...
