Note: A feature of online education is that for training you need a constant connection to the Internet. On the site of the university, where the student is trained, a personal page opens for him, where the tasks, results and recommendations of teachers are posted. In addition, the site can find all the necessary books for learning, manuals and lectures.  How difficult it is to acquire knowledge online depends on a number of factors: from the learner, from the specialty and from the level of the student’s knowledge. Since the training program is tailored for each individual, this makes it possible to shorten the training period. With all the convenience of online education, it is not suitable for everyone. First, not everyone will be able to deal with the information on their own. Secondly, in order to be educated remotely, good self-discipline is needed. A variety of online learning are webinars, the essence of which is that specialists in a certain field prepare topics and speak to online listeners. Such events are often conducted by experienced teachers of higher educational institutions. During the webinar, you can ask questions, take part in discussions of problems and get advice from qualified specialists.
