Studying ethics last thing ? Is it a bad strategy? only, everything, recommend, reporting

onelife1

I covered ethics and GIPS from schweser notes only one day and I barely remember anything. My strategy is to leave it last thing (as in end of October) to cover it in depth from CFAI, after I got everything else out of the way! Is this a bad stategy? How do you go about yours?
I have so far covered Statistics and Economics and i am for the second time doing revision on both and should be finished by 29th. Now would you recommend:
a- to jump to Financial reporting straight after I am done my revision?
or
b- spend a good 4-5 days on ethics and start Financial reporting at the beginning of september?
Thanks
