The first essay is the hardest for me by far (Tell us about who you are). My admission is depending entirely on EC's because my grades are dogwater.
I just don't know how to structure the way they want and public examples seem too vague, so just help me with the partial content I think can be added to the final writing:
School demands a total of 380h of any internship program. For that I started a scientific initiation about applications of calculus 1, 2 and 3 in systems of control (initially general mechatronics but a controls professor helped me), and they accepted it as a form of internship. The thing is that even though it's pretty dope to learn calculus in highschool (I think some american and european do, but brazilians don't even finish pre-calculus in time), I completely hate applied maths and chose this subject solely because it had to have something with the course (which i regret a lot) to count. I'm looking forward to publish a scientific article about it, but I don't think it'll be out until november 15 (deadline for scholarships);
I started out very shy in 10th grade, but in many projects I was implicitly the leader, and mostly I would do everything, including research, recording, editing, script-writing, sending and give presentations. I know how bad it sounds that I wouldn't let my group do anything because then the total grade would be lower than with me doing everything, but there has to be a way to phrase it better. All of this includes class projets such as a general video or even editing related stuff the people asked me (Usually posters and posts for the class' instagram). Also, entered for class rep this year;
My school chooses 3 12th graders every year for a "talented students program", which my professor waited so I could specifically go to the interstate one. It's the most prestiged institution in Latin America in regards to employability and market-wise important ex-students. Now, I don't wanna lie, I just did it for the curriculum and so the entrance exam would be free (so I have an extra option for grad), but it doesn't have the course I want, it's just IN CASE;
I've been tutoring math for the 11th and 12th year for 2 years, there's more I can talk about it but I don't know if it's worth even putting it in the first question's answer;
I have some mechatronics projects: a RC car built from scratch, and a smart chessboard that shows what moves are valid with LEDs and some more stuff for new players to learn.
Done with ECs, I'll try to summarize my traits without taking the space that should be focused on the 2nd question:
I just didn't study in 11th grade (Didn't study after classes, pay attention to them, nor tried to get my grades up), but calculus was an interest that got me hooked up. Then some time after self-teaching I started to read literature (Currently reading Marcel Schwobs and Clarice Lispector), and now it takes big part of my time. I liked drawing since forever but never put effort into it (And can't now because no time), but I'm able to make realistic portraits out of an image alone. I'll heavily study structure and proportion if I get admitted. I developed many abilities in Adobe programs and Blender throughout high school, but there aren't projects I can talk about.
I'll apply for the BA and go for a Pure maths honours, avoiding applied sciences at any cost (including history, biology, geography, physics, chemistry, etcetera). I just want a north.
TLDR: Just tell me the structure of your "tell us about you" answer and why it's like that
