To the student that feels that they did not do so well:

Remember, you are smart in your own way. Don't give up. Good things take time to manifest. That does not mean that you should go out every weekend or weekday. It's about time management and knowing what to do at the right time. Also, be grateful that you went through the struggle of the semester without dropping out and being a failure but rather, you endured all the circumstances and completed the semester. See that as an achievement and a reason to work harder

Do not feel like all hope is lost. It is normal to feel sad or mad at yourself for not doing so great but remember that as long as you are still a student, you have a chance to do better than you did before.

To the student that did well and met their expectation this semester:

Congratulations on doing well. Keep up the good work and enjoy your achievement. Moreover, do not slack off as a result of the enjoyment. Bragging about your achievements can also lead to not doing well. But hey, enjoy because you deserve it.
