Final semester classes advice

I am in my final semester as a CS major, so in typical fashion, I'm hoping that anyone who has taken these classes with these professors can give me insight on what they are like and tips to do well in them, especially since my GPA could be better and I wanna raise it a bit before I graduate!

CS491
CS350 - Itani
CS450 - Islam
CS351 - Raza

I also have an HSS class, but that's the least of my worries.
