It really is going to depend on you. How much time you are willing to apply. If you do the tape course once through you'll need to invest about 12 hours. That way you learn and use it at the same time. Then you have to decide how inclined you are toward studying on your own... well with the forum to help.
No one can give you a time to say how long it's going to take you. You have to do the work if you want to... it can be a week or it can be months... up to you.
