All the video lessons are pre-recorded, these are not webinars. At the end of every lesson there is a practical task. You can communicate with the teacher personally in the comments regarding every class. The teacher comments on completed assignments, points out errors, approves or asks to redo the work. You are not limited in correcting your work, you can make several options, refine the tasks as many times as necessary until the teacher considers the task completed. You have more practice, more feedback, more time. Study at any convenient time for you!
