Ibo man,
Are those DAT scores and grades, hypothetical scores and grades? I saw in the other thread that you're just planning on taking the DAT at the end of this summer. Is 20/20 the scores you're aiming for or is it your first set DAT scores and you're retaking it again in September?! Also the courses you've mentioned, are these courses that you've already took and received those grades or is it the grades that you're aiming to get?
It's always easy to figure out admissions chances when you have actual numbers and grades to work with. Hypothetical situations are difficult to predict because you don't have that specific situation yet!!
If 20/20 and all "B"s are what you're aiming for to aid your 2.5 undergraduate GPA in the application process, you may have some success. One advice, be sure that those science courses you mentioned are graduate level courses, in that way, your new "B"s will reflect a new graduate level GPA instead of buried in your low undergraduate cumulative GPA. 😎
