What should I do about math classes?? Please help!!!

<p>Ok well my school is involved in an early college program- that is they send us high schoolers to an actual college to take college classes. I am a junior. I skipped pre calc and went straight into calculus. Now I am in calculus 2. I only understand half of the things we are learning and the class intimidates me (we do 2 or 3 sections of a chapter in only 1 hr and 40 minutes [my calculus 1 teacher took a week for each section] and the whole class is filled with actual college students that instantly know the answer to everything [my friend and I are the only high school students there]. I feel like such a loser when I am there! I was so good at high school math but calculus 2 has scared me. I liked math enough to consider a science/math major but I am not even sure about that anymore :( I do have the opportunity to take calculus 3 next year (senior year). I was thinking about taking another class because I have a feeling it's going to be even worse. Should I take another math instead of calculus 3? What about my major? Should I still pursue a math or science major? I really need advice...please help me I would appreciate any kind of help right now :'( </p>

<p>P.S. will colleges view me as lazy if they saw I stopped at calc 2? I'm supposed to be rank # one in my grade and everyone will probably be so shocked if I backed down and my other friend advances to calculus 3... :/
P.S.S. I got a B+ in calc. Is this good?</p>
