How hard is triple science Watch
Does it get rid of a social life?
How hard is it?
How stressful is it?
Stressful? Not really, no more stress than say english or history. For me if found the ISA quite stressful, luckily (well in my opinion anyway) she won't have to worry for that.
The difficulty I am not too sure. For me the current spec was not too hard to grasp, and since you can't exactly rewrite science to make it harder, that probably won't change.
I hoped this somewhat helped.
It's quite interesting and it'll be good if you enjoy science.
It's not too stressful - there is a lot of content in triple, but in most topics the further extended part of triple (the part only triple science students do) is usually just a further add-on to what has been learned in additional/core. This is an advantage too as it means you have a clearer knowledge for additional/core. With Edexcel, there are a few new concepts which aren't mentioned in core or additional which you have to learn, the menstrual cycle being one of the particularly confusing, but there's nothing that can't be understood with 30 minutes revision. Also, as someone has mentioned the grade boundaries tend to be quite low so it's easier to do well!
If you don't revise and sit on your backside believe me it becomes very stressful tried that once got a E but when I revised I got A*/A's in mocks. I am not the biggest science lover but when I put the work in I got what I deserved.
