Hey Urmila! I did pass Sections 1 and 2 when they were still called A and B. I actually read through many of the books listed in the “Suggested Reading” list on CLARB’s website and found them really useful, if not a little dry sometimes. I had several of the books from school and was able to find the rest at the library. Even if you skim a few chapters a week, they’re really good resources. Also, I used the PPI books that you can buy or sometimes find for free online. Taking practice tests are really helpful! Check out the EPA.gov website for some of the newer sustainable practice/best management practices info.
I don’t have anything to sell, but look for the Google Group and you can find stuff for free! Hope that helps. Good luck!
