Most electronics design work does not require complex math, and you can go your entire career without ever needing to use calculus for example.
Of course there are some jobs you might use it daily, but I think if you polled the design engineers on here you'll find they hardly need it.
That's not to say it's not important etc, and you certainly need to know the concepts.

simple problem. A capacitor attached to a fixed DC rail ( and GND ). At time t, after the rail is turned on, what is the current flowing into the cap?
What branch of mathmatics do you use to solve this problem.

I'm all ways been interested in the circuits in computer hardware. The careers adviser at my high school said to me "even if i had the aptitude to do an bachelors in electronic engineering you wont be able to get to do want you want to do, because its done elsewhere other then Australia e.g. Intel and Nvidia" That's why I wanna a do an advanced diploma in electronics it requires an less mathematical ability that I think I should be able to handle it. But I was reading some where that electronics technician are become an less of importance in this age, because of the no need for repairing any electronic equipment when you could just get an new one unless for the militarily.

If you get the 3 year diploma you are not a "technician" unless you take a job as a technician!
I'll say it again, your title is not described by your qualifications, it is described by what job you do.
There is nothing stopping a diploma qualified person from applying to jobs that advertise a degree as a minimum requirement. Here in Australia they often just put that minimum as a token of what they expect. There are cases where you may not get passed HR without it, so you go around HR and straight to.
The hard part is getting that first engineering job (with or without a degree), and then you have something to sell yourself with.
I've done videos on job interview tips, and one of the main things is to work on project so you have something to show off and take along. If all you have on your resume if your qualifications you aren't going to stand out, regardless of what those qualifications are.
As an employer, many times I've got people in with lesser (or even no) qualifications but with lots of interesting hobby projects under their belt over someone that got the university medal but otherwise has nothing else to show.

Exponentials are covered in Algebra I according to Khan Academy. Really, Vc = Vs(1-e-t/Tau) is pretty simple.
Now, i = C * dv/dt probably has to wait until Calc I. It can be hand-waved much earlier. If we include a series resistor, it is much easier: i = V/R * (e-t/Tau) V is the applied voltage.

Maybe electronic engineering deals with signals. Here math goes completely off the rails with Laplace Transforms, Fourier Analysis and the ever popular Fast Fourier Transform. Yes, these are just tools but it takes a dumpster full of math books to get them in your toolbox. Fortunately, MATLAB will do the grunt work. All the engineer needs to do is set up the problem. Which always was the hard part!
How about an RLC circuit? Seems simple enough, it simply produces the electrical equivalent of damped harmonic motion. No big deal! A second order differential equation can solve it easy enough. Oh wait, doesn't Differential Equations come after Calc III or, sometimes, after Calc II? Wherever, it's pretty far along the path!
Of course, for differential equations, 'solving' has a different meaning. It's not like x=3 is a result.
All of these things are learnable. There are some terrific resources and even community colleges cover most of it. That is, many of these things would be covered in a two year STEM program - up to the AS level.
