School starts in 2 weeks and I was wondering what classes would be the best to have on my transcript for forensic science and such.

Chemistry, physics are good starts

Chemistry, physics, as Fr. Chuck said, but also Biology and Anatomy & Physiology if they are offered at your school.

What grade are you in and what science choices do you have?

Also, you will need a lot of math courses.

Too late now I guess, but generally get a broad background in all the sciences. One that is often overlooked is stats. That is what it all comes down to and many forensic scienctists lack. Personally, I would hire someone with a strong stats background than anything else -- the rest can be learned on the job or with remedial training.
