All of the content I provide is not sufficient as your only resource throughout your college process. My site covers the intangibles well, but does not suffice as a resource for deciding on specific colleges, planning your major, etc.
I will recommend some resources that can be useful depending on what you are looking for.
The books I recommend are linked through Amazon so here are some helpful Amazon deals you should be aware of.

Being the powerhouse of the college application industry, College Board does have some useful resources on their website. They range from SAT prep to college planning and searching.
At the very least you can expect the content on College Board to be reliable.

Forum sites (like the subreddits on Reddit) can be useful. They are forum sites so you have to be careful to not take every post as fact or true. Still, they can give access to a lot of students, parents, and guidance professionals.
I wouldn't advise spending too much time on forum sites, though. They can function as a decent supplementary resource or as a means to ask specific questions, but guidance professionals and other resources are needed during the college process.
This isn't limited to college forum sites, but be wary of comparing yourself to other applicants. It is impossible to have all the information and it only produces more anxiety for you during the process.
