Millionth 'am I cooked' post of the day

I got my year 1 first semester results back, I think I'm averaging like a 73% or something - was hoping to do a CSP Juris Doctor after I finish my arts degree undergrad. Am I cooked? Should I maybe think about reassessing my prospects? I know there are worse marks to get, but it's a very competitive postgrad. Any advice or support is appreciated.
