Calm down dude, you're not even in year 11 yet. Its not really something you can compare to a year 10 level.
There are the bare basics which you should get in a second but there are also the insane questions that you might not get for a few hours.
Point is, see how you go in extension 1 maths in year 11 because its a big workload to cover all the 2U , 3U and 4U content, especially if you dont like or you're not good at maths. It's not particularly difficult (from my opinion), you just have to do a lot of work.
