I actually would echo HaifaGirl, many yeshivos do not prepare you for the outside (if you need to go), CC will.
That being said, you still have no mastered a derech HaLimud in 12th Grade. There are many yeshivos out there with many different drachim. Be openminded and do a lot of research.
If you have decided at age 17-18 that you will be learning for the rest of your life, and refuse to prepare for any other outcome, then please ignore my comments, go straight to Ponevitch, and immerse yourself in limud Hatorah 24-7.
