I'm thinking of studying Geology at University , and wanted to know how demanding it is to study?

will i be able to hold down a part time job without any major interference to my studies?

I didn't take chemistry in my last senior year (year 12 in Australia) , although i did take it in year 11 and have some knowledge.

i also haven't done physics at a senior level
