I majored in Computer Engineering this year (last month). CE is generally "harder" than CS, but there isn't any big difference. So basically, programming will be the core of what you'll be studying.
Programming languages like Python, C, C++, Java, JS, PHP etc .
Well, I don't think there are any tips that could make you understand it easier, except the usual ones.
You should really be paying attention and try to understand the code when it is explained. Usually we were given the "solution logic" and had to write the code ourselves, which was a really good thing. First of all try to learn the syntax very well, it's really really important, especially in Java. Then understanding the question comes next, so, you'll probably have to read them loads of time.
Practice a lot, don't just read the book and leave it like that. Without working on it, you won't be able to achieve anything.
I don't really know what else to say, just that it needs some serious work to really get it. But if you do, it won't really bother you, except when there's critical thinking. (I hated that xd)
Anyway, I wish you good luck. Oh and if you have prior knowledge to anything related to programming, it will help you a lot.
Hope this helped.
