I currently work as a Trust Officer for a large bank and I am considering the CFA to boost my credentials. I have taken a practice test that had a little over 80+ questions that are weighted similar to what the level 1 exam is. I have scored about 57% on the entire exam. I thought this was pretty good considering I have not studied for the test and have never taken an econ, accounting, or finance class.
For someone with a limited background in those 3 areas what should be the best way for me to study for the exam?
