Extension english in year 11 (Is it worth it?) (1 Viewer)

[periodmami]

Hey guys, I've chosen my subjects for year 11 in 2020:
Drama
Visual arts
Society and culture
SOR II
Maths standard 2
English advanced
English extension

I'm curious if the extension course for English is worth it, considering the workload and the period 0 or 6 class.
I've maintained high marks in English since year 7, receiving over 95% for every task. Considering that, it sounds good, but it is year 10 work, which is more lenient. I do tend to struggle a bit with lots of coursework, and I have other heavy-content subjects.

Did anyone do English extension in year 11 and has any input?

Thank you <3
