This past year I used Achievable to study for the SIE, the Series 7, and the Series 63, and passed all the exams on my first attempt. 5 years ago I used Kaplan to study for the Series 65 and it took me 3 attempts to pass.
Achievable’s test bank of questions have a different style and tone than the real exam questions. The 63 was my last exam to take and I was not feeling comfortable with only Achievable’s questions, so I purchased ExamFX for their practice exams. I do not think I would have passed the first time without ExamFX because ExamFX’s questions were more like the real exam questions.
