Tuition for cuet

Hey all, so I'm planning to appear for cuet entrance exam. Since it's only 4 months away and I have no idea how and where to start, what do y'all think should I do. Should I invest in a tuition or should I do self study. And if i go for tuition, then which one has got a good faculty according to you. Also, is it easy to score above 650? And i also wanted some career advice. But that's for another post.
