Work hard to fix it. You can still bring your grades up. Assuming worst case scenario for second semester (another 2.5), you can still raise it up to a 3.5. But also you’d have a really great grade trend if you did work that hard for the rest of high school which would help a bit. I was in a similar situation with a 2.5 my freshman year and then had a rough start sophomore year but raised it to a 3.36. Now it wasn’t the best gpa, and there were circumstances that led to it, but I have don’t well on standardized tests and even received scholarships from some good universities! Im still waiting for some decisions, but if you do pickup your game, get stellar grades for the rest of high school, and ace the standardized tests you’ll have amazing options out of hs!
