all the S7 material is about the same. I feel the best thing is to take a 5 day crash course to learn it. You can learn the material in about 5 days, learn what the test mainly consists of (options and munis more anything it seems)
in your zip code, search for securities and insurance exam prep testing. take a 5 day crash course. Then take several practice test question exams for a few days and you should be good to go.
