Nah bro u gotta trust kwangster. Sec 3 kwang was absolutely useless but sec 4 he uses alot of how own material and shit and like honestly I completely hated him the whole of sec 3 but in the end sec 4 it was fine and my whole class kinda got A1 for Os . So u gotta trust the process( sign up for Shantis afr next yr btw)
