Q: Please grammarticary correct my opinions.
A: I'm guessing what tense you are using here (you jump between it a bit) but here are some pointers
1. The damage when it doesn't go well will be too big
2. They'll keep the negative feeling forever
3. There is no problem studying for the test a little before the exam
4. It is not late even after entering
5. Getting in doesn't determine the value of life
6. ...but love is a precious emotion to enrich into our lives
7. Such a feeling cannot be restricted by a college-orientated notion
