Anyone who's willing to cheat isn't worth flying with, or employing. It really isn't hard for RYR to contact your FTO to verify your results.
The only person who put you under this pressure is yourself benish. you signed the dotted. No one forced you. You may have to fid something else in the mean time that isnt a main stream airline. OR you may find another airline that doesn't mind a few failures in GS exams. At the moment all airlines that are recruiting, are only calling for selection those with the best results.
