This really depends on you, individually. While in general we recommend studying for 120-150 hours total, there is no true set time for how much it will take.
Some people take two weeks to cover the basics and practice questions like mad and end up passing. Others take a year due to their work schedules and life situations.
If you study 2-3 hours a day, 5x a week, you are looking at 10+ weeks of studying.
