will i be able to do medicine or engineering without doing math methods in year?

[Tamara beeo]

hello everyone, my name is Tamara and I'm currently doing chemistry, English, further maths, VCD and economics in year 12.
I'm really interested in doing medicine or engineering but I'm afraid I don't meet the prerequisites, IM SO STRESSED HELP. melb university and other universities have prerequisites of math methods or specialists math to do the courses. I'm not really good with math that why I choose further math because I can just rely on the calculator. the problem is I didn't go to school from grade 6 to year 8 due to immigration and was not allowed to go to school because I didn't know the language of a Georgia, but I'm doing very well now my average for each subject is between 78-92.
I just wanted someone with more knowledge to tell me if anything I can do.
sorry for my English
