Classroom learning allows for direct interaction between learners and the trainer, as well as learning through hands-on activities. With online methods, learners can move through content at their own pace, and even revisit content for additional clarity.

This helps to balance a classroom that contains both quick and slow learners. Every student can practice and tackle new material with timing that is perfect just for them.
