Me : Hello Dad! I've an exam today.

He : All the best son! I'm getting a strong feeling. You'll rock it today. May god bless you!

Me : Thank you dad. Bye! And I hang up the call.

My friend standing beside me chuckles, "Do you do this before every exam?" I answer, "Yes, I feel good and encouraged, and so do they." It hardly takes a minute to call up your parents, but it gives a lot of confidence and makes their day too.

Not calling up parents is indeed a common mistake college students make. For me the most common mistake is treating it like school. When I went to university, most of the people around me came straight from school. They had the thought like children who were being forced to do something. They skipped classes, sat at the back talking during lectures and even didn't do the reading! They were still in "school" mode, thinking that the point was to get through it with the least effort.

For my part, I was there after working in a beer factory for three years. I knew that I had gone to university because I wanted to learn. I wasn't there because my teachers at school made me go, or my parents made me go, or because my friends were all going. I had chosen to go. I think that this put me in a different mind. I read all the set texts and I went to all the lectures and seminars. Don't get me wrong. I had fun too, but I was there to learn and I learnt a lot. I enjoyed it and it was rewarding to learn about the authors, their works, the critic's opinions etc.

The kids around me thought that reading six novels for a module and going to a lecture for each novel was too much work. They would read one novel, go to the lecture for that one and write their essay on that one book. They thought that they were really clever to work out an easier way of doing it. But they were tricking themselves out of an education!

There are other mistakes that may cause future regrets for the college students. A large number of them focus too hard on getting good grades, showing no interest in out-of-class side projects. Some complain that they are too busy because of school. As a matter of fact, they do not seriously treat all the free resources that universities have to offer.
