I'm speaking as somebody who is rather good and interested in maths as well. My opinion is that it is possible to get any study score in specialist maths as long as you put in the effort. For strong maths students, getting a 30 should be possible with a sincere work ethic, doing exercises and a couple of practice exams. For students who are not so good at maths or don't have such a strong background in maths, they may need to put in extra work.
It is not fair to say that what is hard for one person may or may not be hard for another person. You can't say that a 30 in spesh is difficult or easy, it depends on the person who you are talking about.
In my opinion, spesh is a difficult subject, it is far more difficult than methods and the reason why the A+ cut off is the same for both subjects is because of the competition. It is exactly like how you have heats in olympics athletics. Once you get to the final, you are up against the best, this is what spesh is like. I can routinely get a 40/40 for methods exam 1's whilst I will struggle to get a 40/40 for a spesh exam 1 - this is what i mean by how spesh is more difficult
Special at Specialist - your attitude is arrogant and unhelpful, although you might be good at maths, you have to consider that there are other people who aren't so good and you don't seem to respect them. If you are going for a 50 in Specialist - that's great, if you are able to get that, I will be happy for you because I respect people who do well, but you have to learn to respect other people as well, getting a 50 will get you nowhere in life with the attitude you now possess.
