You can't take the basic chem sequence in Australia. I tried. Everything is backwards, and it doesn't help that their semesters are the opposite of ours. She should drop the chem sequence she's in now (it will most likely not help her) and take something else if possible. She'll have to wait to take chem when she gets back. Tell her to take some other requirement, such as bio, b/c it doesn't matter what order you take bio in usually. Also, I don't think that she has to call medical schools and ask if it's ok if you take the premed requirements abroad - she is in an English speaking country and most medical schools will accept anything that your home institution will accept.
