Color Coordination Examination Level 1 Past Exam Collection 2018 Edition This is a valuable collection of past exams for Level 1, as there aren't many problem sets available. The Level 2 color cards have been cut out, but everything else is complete. There are no markings, so you can solve the problems without any issues. For Level 1, repeatedly solving past exams is the key to passing! (I passed the year before last) I recommend solving past exams from as many years as possible. I solved 6 years' worth of past exams over and over again. Thank you for your consideration.
