Condoms Quality

Is this a good idea to keep a condom in a backpack?
For example, say that is completed around after school and kept condoms in her backpack during school hours. When the time comes, do you think that the condom is of lower quality?
No, the condoms in my bag of books throughout the school year b / c my bf does not carry with him. So if you have worked for us throughout the school year im sure it will work for you in one day.
