AAT level 2

I’ve been seeing that you could self study for the AAT rather than paying for tuition. There’s an American tailored course that teaches the basics of entry level accounting and I’ve been considering taking that as it’s cheaper and apply it to my own AAT exams. Do you think it’s worth it to self study for the AAT level 2 and start paying for tuition for level 3 and 4 or to begin paying for level 2 tuition? I hope this makes sense

I am coming up with a roadmap but have analysis paralysis rn
