Shall I try to do all the 1108 Practice Questions on CFAIII

I’ve done the updated IFT mocks & old CFAI relevant questions scoring mid 60/low70s. I’m starting the schweser AMs and so far it’s been brutal… I found IFT had some deficiencies but close to the CFAI format with guided responses. Kaplan seems to focus on the obscure sub topics with heavy calculations, still in the 180 minute format with the wrong online interphase. I’m going to tough it out and try to finish them since I’ve bought the package but I don’t feel these questions are very representative. I’ve heard the PMs are okay…
