The free path, in order
1. Start from the exam objectives / outline — it is the scope the certifying body itself publishes, and where a vendor also publishes domain weightings they are in it. It may not be a comprehensive list of every exam topic. Study against it, not against a course's table of contents. Where the entry below records an exam version RoleMath has not verified as current, confirm on the vendor's page that you are reading the outline for your exam before you study against it.
2. Work the free structured course(s) above to build the skills — first check each one against What to know above, and where a course was written for a different exam version than the one you will sit, treat it as background rather than as your main preparation. Treat official material as scope authority and community material as instruction; use official sample questions where they exist.
3. Free study lowers what you spend preparing, not what the exam itself costs — see what it costs to earn and keep.
Free resources reduce what you spend to study. No resource guarantees a pass, and a course is not the certification.
