<p>It sounds like there is a bit of confusion…</p>
<p>I’ll try to clear up some things though, which I hope will help!</p>
<p>Here is a general timeline of high education:
4 Years of High School –> 4 Years of Undergraduate Education –> Post-Graduate Education (Graduate School, Medical School, PHARMACY SCHOOL, Law School, etc)
You can do your undergraduate education at a different place you do your post-graduate education. UCSD has a undergraduate system, a graduate school, a medical school, and a pharmaceutical school. Each has a separate admissions procedure and requirements. While they are all UCSD, they are not all for you.</p>
<p>Currently you are in high school, so your next step (after you graduate from high school)is to attend a college/ university that offers undergraduate programs (4-Year Institution). </p>
<p>I suggest increasing your GPA immediately. Unfortunately, this means get all the A’s that you can. But if you do get more A’s hopefully your class ranking, unweighted GPA and weighted GPA will increase as well!!!Many schools like seeing a trend of your grades improving!!! Increase you SAT to around 1880-ish to 2000-ish to be considered competitive as well!</p>
<p>Commit to 1-2 extracurricular activities (More if you can handle it!) It is important to COMMIT not just put a half-hearted effort. Keep doing your tennis, that is definitely a +!</p>
<p>All the UCs (except UC San Francisco) and many other colleges and universities around the United States (assuming you live in the US) offer undergraduate programs. (It seems you are interested in UCSD though 
Call some schools and ask about freshman admissions, and go online to see some of the incoming freshman statistics per school.</p>
<p>Honestly your chances of getting into UCSD as an undergraduate are not very good, but there is room for great improvement in your Junior and Senior Years of High School. If you improve your general trend of grades in your junior year and senior year, you will have a MUCH better chance of getting into UCSD.
Another option is attending a community college but you should definitely TRANSFER to a 4-Year Institution after 2 years using a transfer agreement if you decide to take this route. Call some community colleges for more information if you are interested.</p>
<p>Honestly, do not think about Pharmacy or Medical School right now. Focus on your high school grades, SAT, extracurriculars, and tennis. Then when you are in college, go crazy in finding out requirements for pharmacy school during your freshman year and what you need to do during your underagraduate years to go to pharmacy school. Your college GPA is VERY important as well, but don’t worry about when or where you do your undergraduate education at the moment. Take things as they come and you will do well, no doubt!!!</p>
<p>Another point is it is always a good indicator to see if you are actually interested in a certain subject. Take a biology and chemistry class in your junior and/ or senior year (preferably AP Biology and AP Chemistry just as Loncria said). The course load and material in AP Biology and AP Chemistry will give you a taste as to what is to come!</p>
<p>One last note (Sorry I didn’t mean for this reply to be long…), ignorance is not an excuse! Undergraduate schools, graduate schools, medical schools, pharmacy schools, and law schools want their applicants to be knowledgable about their programs. It is an applicant’s responsibility to find out as much as they can about what they are interested in and the requirements and timeline each college has. Colleges assume that when you apply you know what you are getting yourself into. Even though colleges never say that directly, THEY 100% mean it!!!</p>
<p>I think if you take some of this advice, you’ll do fine in whatever you do!!!</p>
<p>Good Luck!</p>
