I personally think that if you are a relatively strong maths student, you should definitely take Specialist.
I was in the same position this time last year - didn't understand the content and had difficulty following the pace of the subject and balancing it with other difficult subjects (methods, chem and lit.)
There's no doubt that Specialist is a specially difficult subject, but you definitely get rewarded for it in the end. Although I found the subject very challenging this year, it certainly broadened my understanding of mathematical principles and helped me in both my maths subjects.
My 2 maths scaled scores were by far the highest of all my scores, even though I didn't get a spectacular score in Spec, it still scaled above 50 and contributed to me getting above the ATAR I was aiming for.
So if you're dedicated, I suggest doing Spec, you'll thrive in both your maths subjects and have foundations for many university courses in the future
