Just passed my 3b2 . Thank you power engineering 101 team. The 3b2 practice exam questions were quite helpful Wording was quite tricky on this one. Lots of turbine, compressors, gas turbine, pumps and refrigeration questions. Some weird admin and cooling tower questions thrown in

I earned my Second Class Refrigeration Operator license, thanks to the course provided by Power Engineering 101.

I just recently did my fireman’s Certificate exam unfortunately I am failed because I don’t know much about boiler operations and systems as I am brand new in the industry, I am wondering if anyone here in the group who can help me out which learning books or resources, question and answers practice or online websites that i can join in order for me to study and learn more about boiler operations…. Thanks
