You can't. Unless your college intranet system is set up for you as students to receive results online then that is the only way. Other than that, I'm guessing you would go to your college to pick up results.
My college have an online results page which opens 6AM on results day
Does your school have an online results service? If so then the time you can look at them depends on the establishment. My college posts them at 8am. But if not then you have to go and the pick up the physical copy.
firstly you never know how you've done. secondly take your results somewhere private.
Its my gut feeling, its never wrong unfortunately the schools like an open plan building- no privacy what so ever and I know as soon as I walk through that door tens of pairs of eyes (THE TEACHERS) will be staring at me knowing my grades- simply acknowledging by 3 grades UUU
