If this code is on your test report
Your Airman Knowledge Test Report (AKTR) lists an ACS code for every knowledge area you missed on the written test. On the A&P oral, each of those codes adds one question to that section, on top of a minimum of four random questions (FAA Mechanic Test Generator FAQ). So if AM.I.J.K10 is on your AKTR, expect the examiner to ask about it. More on how codes turn into oral questions: A&P ACS codes: know your codes before the oral.
