The most important factor is to apply to a range of colleges that are a good fit for you, rather than focusing solely on the number of applications you submit.
It's a good idea to apply to a range of colleges, including a few reach schools, a few target schools, and a few safety schools.
If you're on a tight budget, you may want to limit the number of applications you submit.
Applying to multiple colleges can be time-consuming, so make sure you have enough time to complete each application thoroughly.
While it's important to have options, remember that the quality of the colleges you apply to matters more than the quantity.
