@KyzaD69 As others have said, you won't know how you're going to be affected until you start but there's the emotional resilience aspect as well. When you're in a school, you need to be "present" all the time when you're there and it's difficult to continually be taking days off. I think you're making a good decision - regardless of how you manage chemo, you can take some time to look after yourself. Investigate targeted exercise classes - the Victorian folk can give you info on what might be available; do a Look Good, Feel Better session; sign up for Netflix if you haven't got it...
