@BrainyCells usually SAT doesn’t matter as much as you think. However, because you are an eighth grader, your SAT and GPA have to be higher because they want to make sure you’ll be ready for IMSA, and they don’t accept very many eighth graders. You probably want to have at least a 1400.
For your ECS and awards, you list as well as describe how many hours per week. I also put for how many years I had been doing them.
You would probably have to take a science course online, though I don’t know much about that.
You could probably talk about your trip to Nepal in your essays, where you could elaborate fully about it.
@alwaystired11 BrainyCells is right, though you probably want to have an SAT score on the higher end or above that range. Tbh, SAT doesn’t matter as much (if you’re applying as a freshman) as your essays, ecs and awards, and teacher recs. One of my friends was waitpooled with a 1550, whereas another was accepted with a 1360. Your interest in STEM is what really matters, and you mostly show that through your essays, ECS, and awards.
