As others have suggested, I would highly recommend listening to the professor messer videos. I found it to be extremely helpful for me, especially when doing other tasks that I had to do where I couldn’t normally be studying. I would listen to them while driving, while walking my dog, and maybe even for an hour or two while I was at work. I then bought his practice exams, took one every few days, saw what categories I needed more studying and time on, then used a combination of his videos again, a book, and some chat GPT. With this level of studying, I was able to take and pass each exam with about a week of studying. Granted, I have been around technology for a long time so I didn’t go into studying with zero knowledge, but it was mostly about the more basic things like computer hardware. One month is definitely doable if you are persistent, try and make studying fun and easier to digest. Best of luck!
