In need of extra study for my Dip in Lab technician over the summer? (Australia)

Just about to finish my first semester of my cert IV and Dip combo and while I passed my Chemistry and math it was through the skin of my teeth. I missed out on year 11 and 12 and need to catch up ASAP, barely passing isn't good enough for a course like this one. Would anyone have textbooks, workbooks or websites on science, chemistry, biology and math (AP as well) that I can use to keep practicing and study with over the summer break? I'm worried if I get into 'summer vacation' mode I will forget and when semester 2 rocks around I'll tank. Would prefer minimal cost but if it's worth it I'll head in store to get workbooks.
