Student physics is really a headache. The employment in this line is narrow and the salary is not much higher! Don't study biology if you don't have the heart to study abroad after finishing your Ph.D.
Besides pharmacy, the food industry is another interdisciplinary approach. Jiangnan University is famous all over the country, and its employment is good.
If you have your own interests, you can consider transferring to your favorite subject for further study! But I still agree with interdisciplinary!
But I must remind you here: no matter what subjects you cross, you must ensure that you are admitted to at least 2 1 1 colleges! Otherwise, when looking for a job, you will be even worse!
