I recently passed the SIE by using Achievable, and Achievable only! I studied on 50 different days, totaling up 85 hours. I am a comfortable test-taker who has a basic foundation in finance, but am yet to take 4th year finance courses.
I spent 67 hours on the reading, section quizzes, chapter exams, midterms, and checkpoints. During this time, I attempted quizzes and other exams multiple times to ensure full understanding and comprehension.
The last ~18 hours I spent doing the full SIE practice exams on Achievable. Each exam took me roughly 35 minutes to complete. I was scoring in the mid to high 80s consistently with these exams.
Achievable worked great for me! I highly recommend this service to anyone who is considering it for future exams!
