  • specialist PSMT - NEED help desperately

I've been living in another country and only moved to Queensland in year 12. I've managed to scrape through for most of my subjects for the IA1 but I feel so screwed for the PMST assignments. I've never done anything like it before and it's just so daunting. And I need 20/20 for both to get the ATAR I need for my dream course.

For specialist, we've been given the population of an animal and been told that it needs to be culled. This needs to be modelled using Leslie matrices. I've never encountered Leslie matrices before, much less the Eigenvalues and other matrices others have been discussing to get higher marks. I've watched a few videos on Leslie Matrices but I don't understand how to use it in the context of an assignment. Can someone please help me out? Are there any resources that I can look at or exemplars I can follow? Should I get a tutor?

As for the structure of the assignment itself, I feel okay because I've been watching Joel Sepranza's math videos and they've been helpful. But my real problem is the content itself.

Any and all help is much appreciated !!

usually it isnt leslie matrices in their basic form, it could be an extension of it that you have to research, for my assignment i had to do a lefkovitch matrix (a type of leslie matrix), using Ax = λx, it is known that the eigen value represents the rate of growth, so if it is >1 the species will be increasing in population, if =1 stays same, if <1 it is decreasing which is what i presume your model will show. You dont need a tutor, look at the qcaa past paper high level response. I followed the same structure sheet by speranza and got a 20/20. if u need any more help just ask.
i understand you think you need 20s and 100s to get your atar but i think youll be suprised at what youll get + bonus points for your atar because u do specialist for when you apply for uni, keep that in mind.

    lil N Thank you for your help, I appreciate it so much! I'll try figuring out how to dm you on here.
