Gleim and ASA are both just the FAA question bank with explanations. The question on regs, procedures, etc. are essentially the same as the Chinese question bank. Skip the light plane and FAR 135 stuff - focus in on the jet performance graphs amd weather maps. Otherwise read the Chinese guide and go through the questions, It's really not 8000 - there's a lot of duplication. I stuck the .pdf file on a Nook reader - it's easier than printing all that stuff out.
