Do you need a "course" to excel in competitive programming(CP) ?

i have to do a "summer training" as it is mandated by our college so i came across various "courses" for CP(and they are quite expensive too) but i feel like all this is just business and they mostly target gullible students as they are mostly from lower tier colleges. Now i am confused whether to go for it or not , and as it is mandatory give your suggestions on various other courses or CP course which you think is reliable (NO PROMOTIONS PLEASE). (I am asking because i read few blogs on codeforces itself on how they are scamming and stuff)
