I am currently a sophomore in high school with a cumulative 3.89 unweighted and a 4.2 weighted GPA. My freshman year i had a 4.0 the entire time, but the start of my sophomore year my grades began to decline. My first semester I finished with a 3.77 unweighted GPA, but the start of the second term has been a complete nightmare. In the beginning of the second term I missed 8 total days of school in one month due to being diagnosed with a mental disorder. For obvious reasons my grades have dropped quite dramatically. My current unweighted GPA (after midterms) is a 2.8, I strongly believe this is only because of the amount of school I missed and I plan on getting a 3.8 the coming semester.
Will colleges see this as a good thing or a bad thing? Does doing extremely poor one semester significantly lower my chances of going to a good school?
