Also, if you think that after graduation you will be able to write programs, games, websites or something else, then I’m very upset you, all four years you will solve trivial tasks from textbooks that intersect with little more than real combat experience as. That is, all the same, at work you will have to fill the same bumps as a person without a higher education, since you are there under approximately equal conditions, and of course, the industry is very dynamic, and you need to first draw up a program for a university, then hone it, and then and approve it. And after all this, still 4 years must pass before this knowledge is received by you. That is, after graduation, even if you do not take into account the lack of experience in developing real projects, you will speak languages ​​and frameworks 5 years ago. Do you remember what happened 5 years ago? I can give a simple example, 5 years ago there was still no now popular swift language used by ayios developers. 5 years ago, no one dreamed of decentralization and cryptocurrencies. 5 years ago, we did not have such advanced self-learning neural networks.

But for the sake of justice I have to tell myself, the lack of education does not interfere with my work. BUT at the same time, I still get a crust on the correspondence, although the correspondence is devoid of the main advantage of education in it, I decided to get this education. Since it is better to have and not need than to need and not have. Most of my friends also work without higher education, one even managed to get into a web studio with absolutely no knowledge and learned everything on the fly. To go to study or not is up to you.
