P7 Open Learning

Hi Folks

Could P7 be done open learning and then just go to the revision course as i dont have the funds to pay for the full course and have a lot of free time on my hands so would have time to study it at home?

Also is P5 very difficult as having to decide on weather to choose adv tax or adv Per management. really dont want to do tax as heard it is crazy hard!

But i had an exemption from f5 so havent done management accountancy since uni!

any help would be appreciated
