Is it better to have a B/C+ in Math Honours or an A in regular math?

If it moves too fast for you then you may consider getting into a regular math cl. You will have the rest of your life to learn more about math. When you get to college you will have to take math, period. How much you need to take depends on your school. I am a business major so I had to go through clac two. What math cl you decide to take now will have little to know affect on your acceptance in to a good school. Take whatever cl you benefit the most from and do your best in it. If you decide to stick with the harder one though, that is no excuse to get a C. You need to do your best.
