The format matters less than the teaching
Good online IGCSE Additional Mathematics tuition in Malaysia has three things in common: it teaches the method behind every step (not just the answer), it keeps the class small enough that every student is called on, and it starts from your child's actual gaps instead of marching through the syllabus. Platform, schedule and even price are secondary. When those three are in place, online tuition is as effective as in-person, and often more focused.
