Pre-Calc Honors is definitely a rigorous program. However, if you say that you’re rather weak at math, it would be a good option to go with something you are more comfortable with. Another good point to check is to see if the college major you want to pursue really requires a demanding math subject like Pre-Calc. Furthermore, 3 AP classes might be a bit much, but it depends on the difficulty of the subjects. I’m sure you will be able to get through it if you put your mind and heart to it! Anything is possible.
