Wiley and Becker are almost neck in neck in terms of cost, CPA course features, and quality test prep material. If you are looking for in-person classes, an integrated and easy-to-use app, and engaging video content, Becker may be the better choice.
If you are looking for a huge number of practice questions and comprehensive textbooks, Wiley may be the better option. Both are great courses that can help you pass the CPA exam.
