An iPhone can be a distraction when you're studying, but thanks to Securities Institute of America, it can also be a learning tool. Founded by Wall Street professionals, the learning center specializes in test-prep software—compatible with Macs, PCs, smartphones, and tablets—for 13 series of the General Securities Representative Qualification Exams. (Another one of their programs helps students prep for the Chartered Financial Analyst exam.) Regardless of the exact test, all the team's programs and videos are designed for customization, so that student can tailor the experience to their strengths. A best example of this is the student's ability to randomize his or her own quizzes, selecting topics and a number of questions. Videos bring this content to life, while PowerPoint presentations further tutor students in difficult areas. As a partnership with John Wiley & Sons, the largest publisher of financial information, textbooks are packed with test tips, sample questions, and need-to-know info for exams. For those who prefer a live teacher to give their spare apples to, the institute also hosts tutoring sessions and onsite classes.
