I successfully passed both!
I used several of Wasim’s books for the FE and PE. I successfully passed both! The PE book was very helpful and an excellent guideline. I recommend any of Wasim’s books to future test takes whether it be for the FE or PE. I also recommend the PE course that contains numerous lectures and quizzes. These lectures helped me to understand the theory and how the formulas are used. Excellent course and books that I highly recommend.
