IBEW Local 105

I am applying to my local union in Hamilton, ON. I went in to set up the date for my aptitude test, but the lady at the desk said the test would be 2 hours with grade 12 level math, english and science. I have been studying and taking practise tests online, but they're all only basic algebra and reading comprehension questions. I'm just curious if anyone in ontario would have insight on what type of "science" questions they would ask. I also think its pretty vague saying science questions, like are they mostly physic specific questions? I doubt any chemistry or biology is involved
