Color Coordination Examination Level 1 Past Exam Collection 2020 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 is included. 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 exam the year before last). I recommend solving as many years' worth of past exams as possible. I solved 6 years' worth of past exams over and over again. Thank you for your consideration.
