Excellent job...

Ah.. I remember it well...

After 100 credits I had all A's... 4.0
Then - well - I didn't get an A.... well - still had 3.9
Remember - it isn't about GPA... it is about what you learn...
(said the guy who blew his 4.0)
That said - 4.0 is the way to go if you can manage it...
Keep it up!
