UCLA requirements

<p>So I was looking at the admission requirements for UCLA and it says something along the lines of two out of three lab sciences during high school...
I think I took physical science in 9th grade and then biology 10th grade..I'm in 11th grade right now and I am an IB student so I'm taking a two year course in biology 11th and 12th grade. I don't think physical science is counted as lab science cause in the requirements it said: "chemistry, biology or physics". Basically, I've only taken one science then-biology. Do I need to take an online class in chemistry or physics to complete the requirement for admissions?</p>
