Search Results: hard math questions

Hello everyone, my situation seems to be tragic. I am a freshman at university and I had an extremely low GPA for the first semester. 0.45 out of 4. (2 is the minimum to pass.) I'm studying in the best university in my country so everone here is clever/hardworking af (people say I'm so clever but actually I'm a lazy dog that's why I got low marks haha) I was planning to transfer to an another department, from mining engineering to computer engineering or mechanical engineering, but with this quite low GPA I cannot even pass the class... Also Erasmus (European student exchange program) is so important for me , people say its an amazing experience, it requires 2.4 GPA at last. I have a chance to use my foreign citizenship, leave the school, enter the SAT exam and enroll the uni again with this grade. But the English part in SAT... My English teacher in high school was a native English speaker from USA and she said English questions are hard even for her... Math questions in SAT are child's play in contrast, I answered them all in 2 minutes and got them all correct. I'm an Asian student so its normal lmao. (I've entered an SAT exam for trial) So, should I study soo hard and try to succeed in my department this semester, study first class again to increase my GPA, or use my foreigner citizenship and enter SAT? What's the probability of me for attending Erasmus If I do each of these?
Here are my grades;
CAD- DD
