Practice makes perfect y'all
I had Kabbara for sec 4 TS. He was an excellent teacher in terms of reviews. Often, when students had trouble with a particular question from the homework or exams, he'd happily go over it. However, because this class is enriched math, it was rather harder to follow or succeed with this teacher. Be sure to review every class because it's the only way you'll get good grades.
