Is it hard to get A's at Excelsior University taking 2+ classes?

[Cycle]

I need to get a 4.0 GPA and I will be taking all (60 credits worth) of my upper divison classes at Excelsior University for a BA in Liberal Arts. I have no job and no responsibilities other than school. Is it reasonable to take multiple classes per term and get A's in all of my classes? 

Also, the reason I need to get a 4.0 GPA is for applying to law school. The reason I am taking so many classes at Excelsior University is because I need 60 graded semester credits to get a GPA on my law school application which Sophia doesn't provide.

Thank you in advance
