What are my options for university.?

I am a year 12 student with 60 excellence credits potentially 50 more from externals. I am also extremely confident in achieving scholarship in 3 subjects this year. However through my arrogance in the last few years I have accumulated not achieved credits (30 in level 1 and 10 in level 2). This is due to the fact that I did not study for subjects that I did not like (mostly non quantitative subjects). I am very strong in mathematics and am going to do a math major at university. I was wondering what my options were for universities and what my overall situation means. As well as my usual study, in year 13 I plan to resit all the standards that I got below excellence. Is this a good idea?

In which country are you hoping to attend university?
