Slight career shift after a layoff here...any suggestions on best way to prepare for the Series 65 Exam? First thing I came across on YouTube was Passmasters. https://passmasters.com/securities/series-65/
There are several study guide companies that offere study material - and if you follow their recipe, along with the practice exams they offer, you can generally have succes. Solomon, Kaplan, STC are a few that come to mind. Good luck!!
Follow the schedule of whatever study guide you purchase and as mentioned, buy the package with unlimited test bank questions. I used STC and was pleased.
One additional tip...buy and take a final exam from another company a few days before your exam. It's easy to get used to wording styles so the slight shakeup helps.
