The pre-entry flight test is hardly likely to be anything to worry about. JAR-FCL 1.335(f) states that a candidate should have "....passed a specific pre-entry flight test with an FI qualified as in JAR–FCL 1.330(f) based upon the proficiency check as set out in Appendix 3 to JAR–FCL 1.240 within the six months preceding the start of the course. The flight test will assess the ability of the applicant to undertake the course." So all you have to do is to pass an LPC and, let's face it, no FIC instructor is likely to pass up the chance of earning a bucketful of money by telling you that you do not have the ability to start the course! It will probably be the easiest LPC you have ever taken.
