So I kind of messed up....

<p>Hey guys,
I'm a junior in the last quarter of the year, and I'm already freaking out about college. This year has honestly been very rough for me; for the first time in my life I received a C, in honors precal (pretty darn hard) for the first semester and there is a chance that I might get another C for this semester. Other than those slip ups, I have maintained all As and Bs. However, I'm worried that the Cs will end up hurting me, as colleges don't like to see a decreasing trend. So I would like to know if I still have a chance at any UCs (particular UCD or UCSD) and any advice on how to improve my chances. Here are my stats (apology in advance for the gratuitous detail):
Freshman year:
Honors geometry B and B+
Honors English A and A-
Honors biology B and B
Computers/health A and A+
PE B+ and A
Drama 2 A and A
Sophomore year:
Honors algebra/trig B and B
Honors English A and A
Honors Chem B and B+
AP Euro A and A
French 1 A and A
PE A and A
Junior year (so far):
Honors precalc C
Honors English A-
AP US History A
AP Chem B
Teachers assistant A
SAT scores (only took one so far):
Writing 680
Reading 650
Math 650
Clubs I have leadership in: Extreme Club, French Club, National honor society
Volunteer in:
American Cancer Society Discovery Shop, local hospital, participated in cancer walks notably Relay for Life, American Red Cross
I am GATE identified, a CSF member, and I am in the top 15% of my class
Thanks! Also, sorry again for the length</p>

French 2 A</p>
