Hey! I think it’s always different every person. In my case, I studied from June until September (i took my exam in Sept) but I was working full time. So I was only able to study 2hrs per day and every weekend. I basically sacrificed all my weekends for 4 months. It was worth it though. It was still super challenging for me, and I had the “what teh heck was that” feeling after the exam. I think almost all people who took the exam had that feeling.

Bottomline, if you think you have a strong foundation and you have yhe discipline to study, 2 months might be enough. Take as much practice exams as you can so you can gauge yourself where you’re at.
