be more confident

So, i’ve decided to apply for graduate school and actually go through with it. I’m starting post-bac classes this fall and applying for entrance winter term. I’ve been terrible about my confidence when it comes to getting in and generally making it through the classes. I’m very worried that I won’t be confident enough to write and present an oral thesis or that I won’t be able to get in, or that everyone will be smarter than me. I’m going to test myself and hope the best for my confidence.
