Yeah, you can get a conditional admissions acceptance, but only if you finish the prereqs, and pass them. Just get at least a C in each class and you're ok.
That is true, I wouldn't recommend getting a C in any class. Keep up the habit of good grades. Letting it slip just before going to dental school could hurt you.
Yup. IUSD, for example, cautions in its provisional acceptance letters that "you will be expected to maintain an academic performance consistent with your application." You can't let things fall completely to the dogs just because you got a letter in the mail 😉
