I used Brainie in preparation for the Certificate in ESG Investing and highly recommend the materials. Read through the curriculum once, take flash cards, then supplement with the robust Brainie question bank to drill questions over and over. I felt very relaxed and confident going into the exam and credit this to the Brainie study materials! I chose Brainie based on reviews I came across on Reddit and people swear by it. I found them extremely helpful and affordable.
