Opinions on retaking exam needed.

I took the exam on 3/20 and did not pass. See 'I didn't pass now what' on the exam results forum. Long story short I read the books took some mock exams but didn't write much code. Since the exam, I've been working on the exercises in the cattle drive and have completed the first 5 as of yesterday (no feedback just compiling and running). I have been asked to report to my boss a plan for becoming certified by 4/15. What I need to know is if retaking and passing the exam in this timeframe is reasonable, if so what steps would you recommend to give me the best chance for success.

Well, whether this is a reasonable amount of time or not may really depend upon how much time you can dedicate each day to studying. If you'll be working 12 hours a day from now until then, I'd say that you'll have a heck of a time getting ready.
However, if you're able to set aside a few hours each day to study, I think you can get ready within a couple of weeks.
Obviously, you're already familiar with most of the topics (as you've already taken the test once) - now you just need to spend some time practicing and reviewing your weak areas.
One great way to get ready is to get active in this forum. I see that you've only created 4 posts here. Post more. The primary way I studied was to answer questions around here. I'd look for new questions and when I found one, I'd answer it. (Try to respond before Val - it's usually a pretty futile attempt, but fun, nonetheless.

) If I didn't know how to answer it, I'd write some code and figure it out. This was my basic source of practice and it worked great for me.
Anyway, that's what I suggest. You can't find a better place to prepare than right here. Granted books and practice exams are great, as well, but this place is one of the best.
Best of luck and I hope to hear more from you,
