Do I still have a chance at Berkeley if I retake a cl?

no worries. my friend who got into berk also had to retake a cl (physics). besides your transcript shouldn't indicate that you failed a cl, it will only be replaced with a normal algebra 2 cl and the grade you received in summer school. oh and if you continue to do well in your junior year you'll be fine cause that's a really impressive schedule right there. by the way my friend got a 1900 on her SAT's if you were curious. good luck!
