They will take it into consideration. What is your gpa now? If these classes are helping you break a 3.0, then they will have a HUGE impact on your application and I would suggest to wait to apply until then. If you have a 3.4 and you will move to a 3.6 or somethin like that then it will still have an impact but it would be fine for you to apply now.
It really depends on your stats though. If you have really good stats, then your app could move a lot faster and the classes will not mean anything unless they are just taking care of pre-req classes. Do you have good numbers/ec's?
