I don't know which college you are from. My suggestion is that if you are interested in psychology or law, study again. Double degree has advantages and disadvantages. If you look to the future, the disadvantages outweigh the advantages.

Going abroad for graduate study depends not on your double degree grade point, but only on your credit grade point. Of course, a double degree can be used for graduate study, but it has taken up a considerable part of your time and energy. I began to take a double degree in law in my senior and sophomore years, and my graduation thesis should be written in my senior year. She is a graduate student, otherwise it will definitely affect the postgraduate entrance examination.

If you are currently majoring in science, it is even more strongly not recommended to study for a double degree. Learning this major well will be of great benefit to your future scientific research and going abroad.
