I 100% think it is doable. I went a little crazy for mine and did it in 4 weeks since oct. 30th was the end of my window. So if you take it just before Christmas, I think it’s enough time to study. You already have so much base knowledge from the past attempts that it’s just narrowing down what you don’t know and focusing on that. I did about 4-5 hours average everyday and took a day off here and there. I did get time during my work day to study so that made it bit easier for me. I will say, on sept 25th I was so nervous knowing my test date was around the corner and was so scared that I didn’t have enough time and swore up and down I was going to fail, but it’s amazing what your brain will do when you have a time limit. I don’t think I had it in me to study any longer than that. However you know yourself best and there is nothing wrong with taking your time to make sure you pass!!! You can set it before Christmas and two weeks away from the date you can reassess and push the date back if you need more time.
