My country is 3 year undergraduate system. I think i am not able to get a double degree in math and physics in 3 years. The credits are not enough though i took 6-7 courses per semester. Normal workload is 5 courses per semester and i think a QM should be much more time-wasting than other subject's courses. However, i do not want to graduate with a mathematical physics degree; i want a double. My professor said my university is public university and the tuition fee is cheap so i CANNOT stay for an extra year for any personal purpose. Are there any alternative methods which can break the university policies and extend my undergrad years to 4 years(Intentionally not take core courses so that i cannot graduate?/Pretending i am sick?) My health is deterioring because of the extreme workload;actually i am quite worried about my kidney health.
