As far as figuring out your major, the starting point I usually recommend is going to the department of labor's website and seeing what the fastest growing fields are. That will give you a starting point if you're drawing a blank about what you'd like to do. I'd also recommend looking at YouTube videos where employees discuss their favorite and least favorite parts of their jobs. One of the downsides to a lot of career decision materials is that they don't usually tell you the downsides of different careers, so it might help you narrow down the options you're considering.
I would suggest working hard during the application process and partnering with a trusted adult or friend to help you with proofreading and to challenge each other to make sure you are representing yourself in the best light.
In short, to answer your question… The college application process can be a simple one if you don't put the time and effort into it. My guess is that simple is not what you're looking for if you are preparing yourself to go to college… Make this your first big challenge and show people that you are ready.
If you are looking to get into good schools, this is your opportunity to show these organizations that you're willing to work hard, put the effort into your application.
Similar to all a lot of things in life, the process is what you make of it - Go for it!
