Yep, lol probably even if they're doing the same course as you do, there's no guarantee that the timings will be exactly the same, although it's nice to have ppl you know from your high school, I find it being better to head into classes with people I don't know...so that I can know more ppl.
Lmao, from my school, almost all the girls went to do B teaching either primary or secondary. Then the others went into media arts or foodscience or comp science.
Though its most likely, that if both you and your friends are doing science courses, that you may be able to meet up in the same classes on your timetable.
P.s. XD Though remember, the really smart ppl are those who can keep up a GPA of 75 or above for the first 3-4 years of their preferred course, or even just scoring 75 or above in their first year. Cos like I knew a couple of friends who went to selective high schools in u.s. and got into med, they kept failing either in the first year or the second, so then they moved on to do easier courses like b sciences.
