Good work you have worked your way to this far, I don’t think you would be allowed to skip the Essential level to go to the options. Also you need P2 knowledge for you to understand for P7 better. My suggetion in this regard would be you pick P2 with F8 then next you go for P7, in my opinion this would help you a great deal.
Am doing P2 with LSBF the essential package, I intend to buy the revision package for P1 an P2 soon. So if I buy from you it means i will need to be using your log in details or can arrangements be made to have these changed. You may can get a refund for the Dec 12 papers. Which package did you buy
