Almost all public universities give CS do nothing to worry about. Colleges like Hilcoe and univs like ASTU and AU are the best. Concepts in Maths such as, Matrix, linear algebra, calculus, probability and statistics( most important one) discrete mathematics, number and graph theory... They are really cool cause you use them to solve problems. Have a good laptop. And do something everyday. Like, make something from scratch every week. Don't entire codes and Do be an AI dependent. Don't wait to finish a prog. Language to do a project. Just make something every week. Small or big, make something and ready to fail and correct a lot, it's what's sets active students from the dormant ones. https://t.me/thebookishbunch
