Honestly, I think online courses can work well for some kids but not all, and it really depends on your child's learning style and discipline. My boy does better with in-person tuition for Math because he needs that face-to-face interaction and immediate feedback, but he picked up English grammar pretty well through an online course since he could rewind and go at his own pace. I'd say start with the subject where your child struggles most, see how it goes for a month or two, rather than committing to all three upfront and spending so much at once. The convenience is real, but if your kid is the type who needs structure and someone physically there to keep them on track, online might just lead to procrastination and wasted money, so trust your gut on that.
