how long would it take....

Hi guys, appreciate this is quite close to a 'how long is a piece of string question' but i'm after very broad scopes....so...
i'm planning to do the CCNP security....if i had 5-6 hours everyday for a month how much would be a realistic amount to achieve in terms of the 4 exams? focusing solely on studying.
I've worked with ACS/ASA/VPNs etc so have some practical experience (not much but some) and will have access to relevant equipment to setup labs.
Like i say, i know its not a simple 'x hours/days/weeks/' answer but i just need a rough gaugue or maybe details of your experience studying for it.
Thanks.

Also, why the rush?
Personally, I would watch the series and take notes in week one, then re - watch the series and lab everything up in week two. Rinse and repeat until done.
