hi, i am very interested in attending the university of Notre Dame but i have what in my opinion is a very big set back, i am not good at literature or history. i have a learning disorder that makes it so i process those at a lower level, but i am very good at math and science and am looking to go into theoretical physics. i am in my second semester of my sophomore year and am currently taking pre calc and ap physics 1 and have gotten a’s in honors and ap chem, and ap stat. my gpa is 4.292. also i heard alumni relations are a factor so would my uncle winning the Heisman for notre dame guarantee me a acceptance even though i struggle in lit and history?
You sound like you are very advanced in taking those classes as a sophomore. Keep up the good work.
Get all of the help that you can in the classes that you struggle with; do extra credit, go to review sessions, write and re-write papers. Prepare well for the new SAT or the ACT (of note, the ACT seems to have more of a timing factor, which may impact you more with your learning issue).
Legacy status does help at Notre Dame, but technically only if your parents attended. Doesn’t hurt to have a family member win the Heisman. May help in your essays showing your connection/enthusiasm for the university.
thanks for the help! and i don’t have to worry about the timing on the act, because of my disability i get x3 the amount of time the normal person would get.
I would also say that in order to make your application stand out, you could try taking some SAT II’s (subject tests) over your strong fields - chemistry, math, physics - to make your application stand out! Good luck! 
Your uncle is Tim Brown? He might have some pull. Otherwise be unusual for a 15 or 16 year old kid to have an uncle in his 70s or 80s a la John Huarte or Paul Horning. Great uncle maybe? Also, despite your humanities difficulties, seems you still do very well in school, so I wouldn’t make too much of that. You sound like a strong candidate. The guaranteed admit you speak of is a bit of a reach. You sound like a great candidate, but guaranteed admits are pretty tough to come by. Good luck.
Honestly the advice I would give anyone applying to Notre Dame is to show enthusiasm and be unique through the essays. Notre Dame’s writing supplement had some of the most out-of-the-box questions of any place I applied to. This was extremely frustrating at first, but it really allowed me to show my excitement about ND and how good of a fit it was. I discussed certain aspects of the university not just in my “Why ND?” essay, but in all 3. Even more so than most universities of its caliber, ND looks for character and uniqueness over pure intelligence. Display that and your chances will increase.
If you worry about your future success in literature/history, and the humanities in general, you should be aware that you will be required to take several such classes as part of ND’s core. More crucially, if you want to pursue theoretical physics (and think you would like to continue that pursuit in graduate school), there are much better schools than Notre Dame, including schools with analytics-focused curricula that will not require you to suffer through humanities courses.
