I agree with what have been said,as practice makes perfect and I think there is no need to repeat it again.
so here is something I want to add which I think might help:
1.making daily conversation with your classmates in English,maybe once a week or an hour a day,you can discuss it in class and fix a time to do this.people who want to improve their spoken English should have a place to practise,and it is your advantage to be an English major,so fully use it. Lucky you! :)
2.in case you want to practise alone,try to describe things around you.whatever you see like a glass of water,a bag,or a girl,anything would fit.this could be done by anytime,anywhere you want.
3.another way to practise alone is to speak to youself.it might sond a little bit weird though.
THE MOST IMPORTANT OF ALL,DON'T BE ASHAME OF MAKING MISTAKES BUT LEARN FROM IT.
