I’m applying to pharmacology in the spring but i feel like I’m not ready for it, but there are students in my class who can’t even convert ml to L yet they’re so gun ho about applying to the program.
How do i gain confidence when i know I’m not ready? I hear there’s going to be a timed math test.

Wow…applying and taking a test is a worry? What is the worse case scenario? You don’t get in and change your major to something that you would be more suited for? Stop comparing yourself to other dolts and concentrate on achieving what it is you want in life and go for it.
Instead of worrying about what you DONT know, look at what you do KNOW.
Ask for some advice beforehand on what might be asked in the Maths test but if people cannot convert mL to L then they should step back and ask themselves if they are in the right class.
Good Luck
