I'm looking to enroll in either the 2 week class or the online prep course at Hobart Institute to become a CWI. Any advice on which one should I take. Please list Pros and Cons. Also list of any free websites to take practice tests for anything related to what will be covered on the CWI test. I am pushing towards API 1104.I already own the API 1104 21th edition, AWS 2.4 Welding symbols, AWS 3.0 Standard welding terms and Definitions. Any other info that you think I would need would be helpful. Thank You
