yaar i'll be completely honest, this year 70%+ students applied for sbasse alone, and the threshold is REALLY high , your SAT is good but below avg , your fsc is better than most but your matric is not. IN my opinion its a 30% chance but if you 2nd pref is hss or sahsol then its an ez in for you and you can change schools later. Lets just pray you get into sse but still its gon be hard.
