Hello, I have a predicament. One semester during the summer, my mother made a silly mistake that could have costed my thousands of dollars. Luckily, I handled it, but because of this stress, my grades suffered slightly. I got my first B+ and an A- in two math classes which does not seem too bad, but I had all A's prior. Now, if I maintain A's this semester, I can maintain an overall >3.9 GPA in both my astrophysics and math major. How bad would one semester look in the scope of things if I tidy up and excel for the remaining 3 and a half years I plan to remain in school? Edit: I understand this is just a little bit of nitpicking, but I was curious.
