Jennifer, take this with a grain of salt because I’ve never used Bedford, but I just passed Exam 5 in the Spring and I used TIA – great job on videos. With that said, just doing those really won’t cut it.
I read Werner & Modlin twice and brushed up on all appendices right before the exam. Same goes for the Friedland text, and memorized the nuances between each technique and when they work best/worst.
