From pre-cal to calculus, there is a jump in terms of abstract thinking. Some kids may excel in pre-cal, but struggle with calculus because the kid is not yet ready for that kind of abstract thinking.
I guess if you are really desperate, you could do it with large amount of private tutoring with a good tutor, but it's not going to be effective. The kid may end up with a B, and AP score of 2-3.
The better way is to wait for a few years, e.g., wait until college to take calculus.
But, it also means he won't get in a highly ranked college. so, it's a dilemma.
Or he gets some effective help and crushes the second semester. Nobody on this board is in a position to say what is and isn't possible, as we dont know your DC's specific situation. You're doing the right thing by looking for ideas. Maybe the teaching isn't great (for him). He may have gaps from earlier in the year that are compounding. A good tutor wlll be able to help identify the issue(s). It's not too late, but it may require some dedicated weekends and drilling on problems. You don't say what kind of tutor, but sometimes a peer tutor or in this case a college student (maybe an engineering or math major) might be helpful. Sometimes, as one gets more familiar with material, one forgets what it was like when it was all new.
One more thought in the drilling of problem sets. This is important. Make sure he is not just doing the homework, getting the wrong answers, and waiting to see how it's solved in class. It's always easier when someone is walking through it and you're just following along. The learning happens when you wrestle with it, get the wrong answer, and dig in to figure out what you did wrong and correct it
