How can I get from A1 to B2 in 1 month?

I know I should have started early, but I didn't. Now I have a deadline of some sort, and I cannot wait any longer. Any resources I can use to get it done in a month?

Here are my mandatory conditions:
The resources should be free with no paywalls and no ads. The method should be backed by science, and native speakers must handcraft the content. But it should be free. It would be great if some sort of free online classes by natives were included in this.

Things about me:
I'm special. Even though it's self-diagnosed, I have always felt that I have ADHD. It makes me hyperfocus, and I can do 10 times the work of a normal person.

I won't be sleeping or eating for the next 30 days. That's 720 hours. I read somewhere that on average, a language requires 600 hours. I'm going to put in 120 extra just to be sure.

Any advice?
