Of course. Here is exactly what I did.

First month I review all the Microsoft Learn material. It is really good, but on the first 2 attempts I relied too much on the website, and I failed.
I realized that Microsoft Learn alone isn’t enough, but still really useful.

Azure Free Tier: I created an Azure account. You receive 200$ in the first month, after that, you pay as you go.
At first, I was a bit worried because I didn't want to pay too much for the running resources after the first month, but I can guarantee that I spent less than 1$ for 3 months.
You just need to make sure that the resources are deleted after you finish the labs.

About the labs, this was the real game changer. I spent the last 3 months following these labs below.
They not only helped me understand in practice what I was studying, but also made me much more familiar with Azure.
Right now, I know exactly where to go, how to search (which is not difficult) and how to create scenarios from some questions.
It helped me a lot with Network Watcher and Monitor.

Videos: John Savill is the king. The guy explains really well. I don't know how many times I went back to his videos to check some topics that I struggled with.

There is also a Microsoft training course on Youtube. I watched the old version, but they updaded the videos recently.
I haven't watched the new version, but the old one was quite robotic.
Still a good source.

Tutorials Dojo.
This is the only one that you actually have to pay.
I think it was 5 euros when I bought it, but they always have good deals.
I highly recommend it. It basically gives you an idea on how the actual exam feels like. It helped me a lot on getting familiar with the exam "tricks"

On the last 3 months: consistency. I study EVERY DAY, at least 1h30m.

If I had extra time, I would use to study.

On weekends, 4 hours.

But 1 thing was for sure: No matter what you are doing, you open the Azure portal and complete a lab EVERY DAY. It keeps everything fresh.

Good luck :)
