Need to make ~30k within a month

I am an HSC-25 examinee who just got out of admission phase. I was able to get seats in a few public universities but the subjects aren't very appealing. My original plan was to complete my HSC and prepare for abroad but my family had other plans. Anyway, I already spent a lot of my parents money in admission phase and I can't ask for anymore.

I wish to apply for fully funded scholarships but to do that, I need at least my IELTS done. I am very confident that I will get a band score of 8 at the very least (without any preparation). But I still want to do a 1 month course and give the IELTS exam. So, I need about 30-35k for the course & the exam registration fee.

I am willing to do anything doable to earn this money. Please give me your valuable advices. Thanks you!
