I would share , especially if asked. I believe if I have worked very hard, made the necessary sacrifices to have the time for studying, etc., then I have EARNED those grades.
Your real friends/classmates at school will be happy for you.
And be happy to share in your joy, will want to congratulate you.
One persons' success does not diminish anothers' achievements.
It also gives you the opportunity to distinguish yourself from
those who are not as committed to scholarship
achievement as you are.
It also gives you the opportunity to establish yourself as a leader. In nursing, on every unit, there are those who are willing to assume
responsibility and provide leadership.
Now is a good time to practice your leadership skills.
(A good topic to research on the net.)
You will be someone's role model for sure, whether you are
aware of it or not.
Again, congratulations, you deserve it and have earned it.
