Capt,
First of all, if you were to do a classroom-based course, it would take you exactly the same amount of time as everyone else. Therefore, this probably wouldn't be the quickest way.
So we're left with distance learning.
A typical distance learning course consists of two modules. At the end of each module, you must attend a two-week brush-up course, and then sit the exams. These two components alone will take you 6 weeks. So you must add the amount of time it takes to study the material to the 6 weeks of compulsary attendance and exams.
Bearing this in mind, I would have thought that 3 months is a little short - but someone will probably prove me wrong by saying they've done it. 4 months might be possible, I don't know. The biggest factor would probably be whether you have the motivation to study for consistantly long hours, and the capacity to be able to take in information so quickly.
I would suggest talking to your chosen school, though, because doing things to such a tight timescale could probably cause extra complexities - for example, brush-up courses and exams my get booked well in advance, and might even require you to book your module 2 brush-up before completing the module 1 exams.
