Junior year according to my experience along with past friends who got their act together during that year. Class of 2006. Further more the work load of junior year is more of a simulation of your work ethic, chances are in senior year you’ll have cheesy elective courses, or home periods. On the other hand colleges look at senior year to see someone who didn’t do so hot in junior year and see how they made up for it senior year. Bottom line, want to get into a good university these days? Show them you’re dedicated to the education system and can be a hard worker in society. Be involved with as many activities, clubs, sports as you can. Volunteer! Look up how writing scholarships work. Just read everything you possibly can about the college you are looking at via website. If there was one thing I could change in my past. It would have been to at least turn in my homework. I wasn’t a dumb kid, but I was rebellious and immature. Keep that G.P.A. shining in the 3.3’s and up and I think you’ll be ok! Good luck!
