Regents

I am so Afraid to fail the regents. This year i have four to take and i don't know what to do. I don't want to fail, but i'm afraid that studying won't be enough. For example, global and science are going to be ridiculously hard. Their is so much to remember and cram. I hope that i will be able to cram most things because if i fail my summer will be terrible. My parents and sister will be disappointed and i will feel terrible myself. I hope that i pass, i hope that i pass, i hope that i pass. I NEED HELPP!!!
