Failed Series & second time
Failed second time on series 7! Used Kaplan material only. Have series 6 and industry experience of 10 years. Please help with your suggestions and advice.
I would try different material. I used STC for both the 7 and 66 and passed both the first time around with an 80% and an 86% respectively. They also have an instructor hotline that you can call and speak directly with a trainer should you not fully understand something.
