If you dont have the motivation to push through it from the start, personally, I dont think it may be worth it for you. Its not all that easy getting a perfect 4.0 in prereqs and a TEAs score of 90+. If your doubting your ambition towards the requirements already, it's going harder to motivate yourself to finish the requirements when classes and tests start to get tough. There is a lot of competition, like you said, and there are a lot of people hungry for the opportunity to get into the program. On a brighter note, if you do decide it is worth it, you already know what is required to get a spot in the program, now you just have to do it. It's very doable but you have to have the motivation for the 2 years of prenursing.
