I passed PE structural exam in Oct 2019 luckily. I was assigned to a design build project since May and the whole team (~5 people) have been working over 50 hours ever since till Dec. I told my PM and my supervisor that I will be taking PE in Oct in Texas (I work in NY but due to immigration status I can't get it in NY). And they all forgot that my PE thing until 1 week before PE exam. I started to study in June, e.g. on every Sat and Sun. but I thought I would forget all about it when it comes to Oct so I stopped. Then I started again in August. I worked around 8 PM everyday and took EET online classes to 12 AM. I had to work also during weekends. I also bought a lot of practice books from Amazon but it turned out I had no time to finish them all. During the exam week, I told my PM that I really need to squeeze sometime to study so I worked from home and I need to take the flight to Texas on Thursday and the exam is on Friday. But until Wednesday of that week, they still gave me assignments and I had to finish them because the project I was working on was one of the biggest projects in my office. And my company doesn't expense any cost, only a $3000 bonus (and it needs to be taxed) when you pass.
So based on your situation, time isn't a matter for passing the exam, you need to focus on your weak areas and try to do as many practice problems as you could.
Best of luck on your 4th attempt!
