Personally, I suggest not to choose Shenyang University. The best environment of these three schools is Shenyang Normal University. I am a student of Software College of Shenyang Normal University. As everyone in Shenyang Normal University knows, Software College (Computer Science and Technology belongs to Software College) is a compound of Shenyang Normal University, which is very weighty. It is a place where there are few boys in Shenyang Normal University, with a good male-female ratio and more boys than girls. And the accommodation conditions of Shenshi software are good.

Shenyang Polytechnic School is also very big, but its location is relatively partial. Although it is also in the university town, it is very remote. But I think it is a science and engineering school after all. It should be good.

Shen Da, my personal impression is not very good, and I am not very clear about Shen Da.

Also, you should note that computer science and technology in Shenyang Normal University can be divided into two categories: normal and non-normal. Non-normal classes are not in software colleges. But non-normal tuition is cheap.
