If you are in a second university, there is still hope to apply to a second-or third-rate university in the United States, provided that you have excellent grades in college for four years and better GRE scores. Three books are not clear, and I don't know the specific situation of your school.
When applying for studying abroad, your academic background is very important. I think it's better to go to a famous domestic school for postgraduate study. Your undergraduate background will not be discriminated against in the domestic postgraduate entrance examination.
I repeat, I think you have potential. People who have confidence in themselves have taken a big step forward. The influence of undergraduate background is still great. It is too difficult for you to apply for a good school, and it will be difficult to take the postgraduate entrance examination. It is difficult for people with poor environment to reach the top.
In my opinion, your situation should be that you didn't study hard in high school for three years, didn't do well in the college entrance examination, and now you do better in the exam than before. This kind of person is most suitable for repeat reading and will make the greatest progress. The premise is that you have enough determination and perseverance
I'm a maritime student now, and I regret that I didn't repeat it.
Don't come to maritime affairs if you want to go to graduate school. Maritime undergraduate employment is very good, but it is not suitable for those who want to continue their studies because the academic atmosphere here is not good. Go to college.
