Is this doable?

So right now i'm DZ level 43. I really want to get to 75 to get the aug blueprint but since i'm playying alone most of the night time i'm having a really hard time killing stuff in DZ 1 and 2 fast. It feels like it takes waaay too long. On top of that i did some fast calculations. 1 mob gives me 201DZ exp. And i need 28k that means i have to kill 139 mobs? Will that mean i will need to kill 4448 mobs to get to 75? lol! :P That seems almost impossible for me to get to before tuesday
