dont just go through the confuser.
read the books and understand them but dont study them as u will end up falling asleep. as long as u understand what your reading you will start to understand the thought process used in all of the subjects. once you finish the reading do the practice questions on the confuser. if u get less than 90 percent see what ur doing wrong and re-read that chapter. do the same set of questions again and you will pass realy easly.
if your planning to do your atpls then this will be the best way as basic knowledge is already in so you will grasp everything else faster. when i did my ppl, i did it the way i did above and had all my exams done in abt 6 weeks. ATPLs though needed some real studying. good luck!
