Hey, I was in a similar situation to you as well. Let me give you an honest impression of my experiences.

I came into Undergrad with no prior experience with Comp Sci, and I've gotta say, I've had a lot of difficulty (still having problems -_-). I actually came into Comp Sci from a Biotechnology background.

It's tough watching others with previous experience fare better than students with little experience. And a lot of students in the CS program attend with prior experience, say from high school and whatnot.

People chalk it up saying "It's easy! Anyone can code!" But it's not as easy as they make it seem. There's a big learning curve, and the university you choose to attend can make or break your interest in the subject.

My University makes things really difficult for the students with the intro courses being purely weed out courses. And right from the start students are thrown into super difficult courses.

So make sure you pick a GOOD university known for good professors in the CS department. That will impact your experience. My professors have been the highlight of my negative my experiences in university. My University doesn't really hire for teaching potential. They often hop around not really caring what the students are struggling in or really teaching good for that matter. It's been mainly reading things up on my own. This made the transition from Biotechnology to Comp Sci difficult.

But it's not all doom and gloom. It's pretty satisfying at times. You struggle a lot, but there's a moment when things just..click. And everything falls into place. You'll be struggling with a piece of code for awhile scratching your head but then all of a sudden you figure it out. It's a pretty satisfying feeling.

Don't let me scare you away. No matter what you pursue you will encounter difficulties. But if you keep an open mind and study and keep moving forward you'll be fine.

Just make sure to research your University's program before you jump in.
