Real feedback from OR-JP candidates on Reddit.
"put off studying the code section for weeks and panicked with like ten days left. ran thru the practice questions on orjpexam.com every night after work and it actually stuck. passed first try, still kinda surprised."
"honestly the math part scared me more than the code, all that volume and offset calculation stuff. found a site that broke those problems down step by step and it made the actual exam feel almost easy. wasnt expecting that tbh"
"took it once already and failed by a couple points, mostly on drawing/plan questions. second time around i focused alot more on reading plans and doing bill of materials practice, recieved my results last week and finally cleared it. relief more than anything."
