Please help me with corrections. Thank you so much, this is an IELTS essay

These days, in most of countries, it can be seen that people, and particularly young people, tend to go to universities or colleges. In this essay I will outline three reasons why they are going to universities and colleges more than ever before.
Firstly, there are some people who say that they attend universities in order to find a good job. Nowdays, most of companies and jobs require one to have a degree. The conditions for getting a job have changed. In the past, it was not necessary to have a university degree. For example, one who is interested in becoming a journalist, has to have a certification. Now young people know that to gaurantee their future, they have to go to universities. On the other hand, there are many other people who have jobs but they wants to advance in their job. So for this reason also, even many  older people attend universities.
Secondly, there are some people who attend universities because they have a nice time and enjoy socializing with other people. They believe that the best time in their life is university life, when they are among people their own age. Also, some people say that they like going to universities just for travel to another countries, and visiting people there, and living some time with them during their studies. There are many kinds of scholarships for which people can apply to go to other countries to study.
Thirdly, interest in a special subject is another reason to attend universities. They say that they are eager to know more about the subject, so they attend in order to focus on their subject and study under professors who are experts about the subject and to use the facilities in the university.
In short, there different reasons to attend universities and colleges, like finding a good job, getting promotions in job, gaining high prestige, being in touch with other people or being interested in a main subject.
