What's ur opinion on Entrances

(16F) So hii guys what's y'alls opinion on Entrances? I'm planning to take pcm+cs. My parents been asking me to go for entrances but I know nothing about em. I'm not a hardcore inteligent woman , just abt above avg student so I'm not really sure about writing entraces cuz duh, it's hard and is competitive. The thing Is I don't care enough to put all the hard work. Thats the main reason why I'm not getting great marks so like what should I do!?! Not doin neet fs idk about JEE nd some other exams like CUET and etc. Please hit me up if you know alot about entrances ,career and shyt cuz idk man.
