That'll take away one day from us though? and LSAT is on Dec 5th ........

i am 25 and graduated with psychology, I wrote LSAT last year December 2015 and did a horrible job at it. I am taking LSAT again in Feb 2017 and currently working as a youth worker in Canada.

My Biggest worry and question is, my Gpa in my undergraduate studies literally sucks, I am sitting at 70%. I have decent amount of community work. If i ace my LSAT, for example get over 160, what are the chances of me getting into law school? without having to repeat or upgrade my grades in undergrad. A lot of people are advising me to go back to school and repeat another semester and bring my grades a little higher, but repeating one or two semesters at the university again won't being my GPA in 80%. Plus I don't want to wait till i am 30 to go to law school.

did not attend last time, I am pretty new here ...

Please advice me on what i can do.

Thank You
