Проверьте эссе на ошибки и по возможности объясните их. Заранее благодарю.

Many people choose to study online these days, and not to go to lectures. Some of them become very good professionals. There are lots of pros and cons of learning online.
Without doubt, there are many advantages in favor for studying online . First of all, students will have free time, because someone have very busy schedule or if the student is ill, he will be able to learn at home. In addition, sometimes students are tense before the exam, as a result it’s hard to go at lectures and to prepare for the standings at the same time. Therefore students better stay at home and learn to standings. Some students argue that lectures sometimes is very boring and you could get the extra information that you don’t need. As in internet you can find knowledge that you really need.
However, learning and teaching online does have certain disadvantages. The first that students must hear another opinions and learn to speak. This is important throughout life. That’s way how we get new friends and communicate with them on different topics. One argument against studying online is that you can’t ask teacher that you understood. You find some information and task in internet and this is good for your study, but sometimes lecturer can give you advice and experience which is impossible to find in internet.
In my opinion better go at lectures. Maybe it will be a waste of time, but it’s a great chance to get new friends. It is wonderful when you can ask the expert some questions and he will personally reply to you and advise something
