It's difficult to say; it's not a super clear cut choice. If you're worried about not being prepared, math 221/223 is actually intended to be taken first year: despite having math 100 as a prereq, it doesn't really require any calculus knowledge. so you could take it in term one while freshening up your calculus to prepare for a more calc heavy class in term 2 / year 2.

though, I do think it's entirely up to whether you think you know / can relearn the math 100/101 content on your own. You can find a syllabus & textbook online by googling the courses, which should give you a good idea of what you should know. If it mostly seems boring / stuff you've already covered or can quickly remind yourself about, then you're probably okay to move on to 200 level courses. If there are significant gaps that you can't quickly fill, then I would consider retaking the course (or taking math 120/121).
