I started using achievable after my 2nd failed attempt of the SIE. I was using Kaplan before hand. Not saying Kaplan does not work it just was not working for me. Achievable was easy to comprehend and once you study to understand the material the information on the exam is no different. I tested and passed at at 85% readiness score with achievable.
Hi @Tangie, congrats on passing your exam, and thanks for letting us know!
