There is no free tier, and here is why
Everything is paid: the lessons, the calculators, the decision wizards, the glossary and the review system. None of it is carved off as a sample, because the parts are worth much less separately than together.
What is public instead is the evidence. The full syllabus lists every module and lesson with nothing held back. The front page prints a figure this product computed and a glossary entry in full, so you can judge the arithmetic and the writing before you decide.
How the 12 months of updates work
Your purchase includes every lesson and revision published in the 12 months after you buy. When that window closes, nothing is removed and nothing stops working. You keep everything you have, permanently, and there is no renewal to decline.
