Cheapest Massachusetts Reinsurance Intermediary Broker courses
Ranked on price, and only among courses that satisfy a route to this license. Exam prep is listed further down but not ranked, because it does not qualify you.
No national seller sells a course for this license. Section 177O(D)(1) does say the applicant "shall take a written examination", and there is no such paper on Pearson's list of every examination the Division gives and no mention of one on either of the Division's reinsurance intermediary pages, so there is nothing here a seller could prepare anybody for.
