Pre-pharmacy is hard if you think that you are going to have a great time, and complete requirements really fast, and get accepted. You need to be serious about your education, and sacrifice things that you actually don't want to. It is just a matter of decisions and time management.
Unfortunately, I believe people who do not have a "scientific mind", are going to have way harder time in pre-pharmacy and pharmacy school as well.
Usually, a scientific approach is a mechanistic approach, step by step, or sequence of things that a person must be able to imagine it in their brain. This does not happen in other courses.
Then, when you get to pharmacy school, you will have to memorize TONS OF TONS of drugs, and how do you make sense of them? By mechanistic approaches, this drugs goes to here, then changes conformation, and positive feedback, and enters here, exit there, and is secreted by the kidneys thanks to this and that etc...
Otherwise, it would be a bunch of names of drugs really hard to memorize.
So, as I say, it will be way harder, if you don't have the aptitude, or deprive yourself from learning it. good luck 👍
