Well, I'm assuming that you'll apply to dental schools around the end of junior year and the start of senior year, so your senior grades won't be included (if you do). Just wanted to let you aware of that too.
Like Blarelli said, a GPA of around 3.4+ with a sGPA of 3.4+ is what I believe to be the average for the total GPA of admitted applicants.
So to some schools, those may be exceptional, mediocre, or poor statistics. Mostly depends on which school you're aiming for.
So if you're around there, you should be in good shape. Just make sure you do decent on the DAT and have some experience in the dental field.
And also, do something that makes you STAND OUT from the other thousands of applicants, because if you just have the same stats as others students, admissions may just ignore you. You have to sell yourself to them, show them why your special.
Peace and Good Luck!
(I'm a soph too, but much lower sGPA haha. Guess I need the leck more than you
)
