I agree with dvlpr75. Definitely use the CFA exams, and every practice exam you can find. Obviously it doesn't do you much good to keep using the same practice exams over and over.
With Level I, you can get away with not doing so well at PM IIRC, but Equity, Debt and Quant are just too big to not do well on across the board. I see that you used Schweser, did you consider purchasing the curriculum as well, or perhaps leveraging a review course in person?
The test can change from June to December if there are any changes to the LOSs, so you definitely want to look into that if you're going to use the same materials.
Don't give up! Remember that the majority of people that eventually get the CFA fail at least one exam, if not more, along the way! Keep going!!
