I think you can do this for sure. I'm also working full time and need to pass everything in 6 months, while in busy season. I had a head start through the holidays though.

Block off at least 2 hours a day to study. I'll be doing this during "dinner break". This should get you through 1 - 1.5 Becker modules per day Mon-Fri. Try to do 5-6 hours over the weekend to finish out the chapter. Start doing cumulative reviews as you go so you don't forget stuff.

The biggest hurdle for someone working our hours is getting through the material. Try to stay on pace and keep doing a little everyday and make sure you are understanding the material so you can easily recall it later in review. I read every MCQ answer, right or wrong, and try to explain to myself in layman's terms how the answer is right. I then make sure all MCQs are answered 100% before moving on. Even though this takes longer, I think it helps weeks down the road when I come across that question again, since I didn't just memorize the answer. I may stumble on the math at first, but I quickly remember.

Pay attention to score release dates and maybe plan for any retakes quickly 2-3 weeks later if you just missed that 75.

People may disagree, but I would leave AUD and BEC for last since you already passed them, and having to wait a whole quarter for FAR or REG score releases next year sounds awful if they happen to spill over to next year.

Also, plan your PTO wisely, if you are willing to blow it on the exam. A week off before an exam to do a massive final review would be helpful.

Lastly, don't let it stress you out. You'll start feeling like you should be working while studying, or studying while working. This will burn you out. If I had the option, I would wait to schedule my exam until I was starting final review, just to take a little pressure off myself. Sometimes work or life comes up, and you can only do the best you can.
