Messing up Junior Year
Am I understanding you correctly that your grades dropped form a 100 to a 99.6?  I mean a 99.6 is still excellent work unless perfection is your standard. Regarding the extra curricular activities, pick two or three at the most, trying to do too much never works in the long run. I routinely review scholarship applications at the college where I am employed. When I see a long laundry list of activities I often question how much the student really contributed. Many students today seem to be more concerned with resume building through a variety of activities rather than developing, in greater depth a smaller number of activities. Grades still matter but don't try to be perfect, just excellent.
