Motorcycle endorsement

I don't know much about motorcycle driving since j haven't done it once in the last 18 years.  But I decided I would go ahead and get my motorcycle endorsement on my idaho drivers license so that I could have the endorsement on my international drivers license when I go to Vietnam, and therefore I would be legal to driver a simple old scooter when I get to Vietnam. They recently (in the last year or two) started to accept international drivers licenses without a need to convert it to a separate Vietnam license.

So I went in for the test today and after waiting about 30 minutes I paid my 3 dollars to take the test and I walked over to take the test and realized that I had only briefly skimmed the manual a couple times, never going into much depth.  I  eeded to answer 20 of the 25.questions  correctly or I  failed.   The testing program tallied what I got correct and what j got wrong,  and I missed 5 of the first 12,  if I got one more wrong I would fail the test on the spot.  I don't  remember  how bad I got the first ones wrong but when I realized that I don't have a single additional one I can miss I spent much more time making sure I was positive of the answer before selecting.  I didn't miss a single additional question and I passed the test.  Kinda nerve racking, since I never barely scrape by at anything. 

Anyway, I now have an instructional permit and I can drive around and them I will go take the skills test with a a dude named Paul for 10$.
