How much of a bonus do i need to clear?

[EsandWhizz]

I signed up to Hollywood poker through 2+2 bonus scheme and i took the max sign up bonus of 1250 dollars with Hollywood. The bonuses come in 5 lump sums and i was wondering if i have to clear the full bonus to get my books as i only play 50 nl and this could take me up to 12 weeks or do i get the books as i clear each 250 dollar bonus. Thanks for any replies.
