Somebody needs to take a chill pill. I don't see why the OP needs to get so hot under the collar when it is suggested he take the full course instead of challenging it.
OP, nobody is saying you MUST take the course. it's only a suggestion. If you're getting so worked up by silly recommendations from peeps on the internet, what's going to happen when you get worked up with a gun in your hand? Control your temper. Chill out. YOU are the one who decides to challenge or take the course so don't feel like you HAVE to do anything people on the internet suggests.
I was shooting since I was 10yrs old. Got my FAC and hunting lic when I was 19yrs and owned firearms till the FAC and restrictions kicked in under Kim Campbell. I stopped shooting for some 20yrs and only now started back. I could have gone and challenged the exam but I chose to take the full course and I'm glad I did because I learned how the examiners wanted things done. I certainly don't regret taking the course as it was a refresher AND I became familiar with the workings of the guns used for the exams. You're not just paying for the course content but you're also getting valuable hints and tips from the instructor which would help you pass your exams.
Just my 2¢ CDN worth.
I agree with Trinimon. My story is almost identical! shooting as a young teen/adult, left it behind for 40 yrs, wanted to get back into it. I took the course and I'm glad that I did, there's no way that I would have passed if I didn't. It's pretty easy! heck, if a 60 yr old wheezer like me can get in the high 90's test scores, well you gotta know that it's easy.
Pay attention in class, read the manual ahead of time, study! you will be proud of yourself when you get your license.
