Hey guys, do you think I should even consider applying for dent schools with a sGPA lower than 3.0? If I get maybe a 19 or 20 on the DAT, do you think I have a chance or should I go for one year masters then apply?

I'm freaking out now
🙁
There are many different factors that could play into that decision:
1) Are you black, hispanic, or native american? If so, then apply.
2) Are you from a state that only accepts instate (i.e. Mississippi), if so, you could consider applying, but no guarantees
3) How low is your GPA exactly? If it's a 2.99, then you could apply. Still don't stand a good chance, though.
If you have a sub 3.0..you need a lot higher on the DAT to get noticed. The sub3.0s who interviewed (that I know of) had 24+ scores on their DAT. It really is a numbers game for sub-3.0s. Someone with a 3.2 and an average DAT can get away with that low of a GPA if they built orphanages in Africa or something..but a sub 3.0 can't. No matter how much of an outstanding application you have, in terms of references, publications, shadowing, awards, etc., you either a high GPA, a high DAT, or both.
I would do a Master's if I were you.
