@youngretired: Going for exam without doing all questionbanks to 100 % then you got to not fear failing. But my question is about the Performance exam since you did it in Poland. Did you factorize the answers for LDR or only factorized when it was written that it is a commercial SEP flight. Because question bank recommend factorizing most LDR (not all actually.....) but in the comments they say only factorize when its clearly written its a commercial SEP flight.....
As for the exams without graphs or calculation I can really not find them hard. Just understand the stuff from bristol groundschool online and do all the question banks. The only exam that had more than 25 % unknown questions was Operational Procedures for me but it still was not hard to pass.
