right so im needing to get my drivers license finished but have a small feeling that i will fail from some stupid little thing buuut i got to thinking of buying a314 and maybe either is or ih and use 1 spray of a314 and the other and then go take my drivers test because my idea behind all this is that to the instructer i would seem like i already knew what i was doing and that the test is kinda unneeded etc let me know what u guys think or if this has already been done etc
It might help in a number of ways - not least because the self effects of a little A314 could help you be more cool and collected on the day - Which would help you avoid those stupid little mistakes that can let you down. Have you tried wearing a shot for a lesson to see yet?
Personally I would tend towards A314/IH to help project a more competent and in-control feeling. Using IS might appear to be making a little too light/carefree of the situation. 
Also remember that diffusion can hit hard in the confined space of a car, so don’t use too much of either and apply early enough to let the scent settle fully.
i was actually wondering what the effects would be on the other thats monitering my test and how they would change
