Didn't get the last week off...

Hey guys need some advice here. I could not get the week before the exam off because one of  my colleagues is on his annual leave and I have to fill in for him. I might not even get this Friday off. I work from 9-7 and am really exhausted when I get back home. Any advice on how I could best spend my time? So far I have taken 5 Mocks (Including CFAI Mock) and am averaging roughly 75%. 

Thanks
