Rona Aydin is the founder of Oriel Admissions, a Princeton-based college admissions consulting firm advising families nationwide on elite university admissions strategy. An Oxford University graduate, Rona leads a deeply experienced team whose distinctive 360 approach treats every part of the application - academics, testing, activities, essays, and interviews - as one connected strategy.
Stanford denies most unsuccessful early applicants outright, so a deferral is a meaningful signal. Here is what being deferred from Stanford means, why the small deferred pool changes your odds, and exactly what to send.
Princeton publishes no deferral statistics, and deferred files get a complete fresh read in the regular round. Here is what a Princeton deferral means, how the second review works, and the 30 day plan that gives it new evidence.
Yale defers roughly 60 percent of early applicants by reported estimates, and about 5 to 7 percent of them are later admitted. Here is what a Yale deferral means, what Yale explicitly asks deferred students to send, and the plan that converts.
Colleges receive both GPAs and trust neither as a ranking tool. Here is how selective admissions offices recalculate, why weighting formulas do not transfer between schools, and what that means for your course selection strategy.
Nearly every selective university rates course rigor as very important. Here is what the most demanding rating means, how counselors decide it, and how to build a schedule that earns it without collapsing your grades.
Elite universities state no preference between AP and IB. Both count as maximum rigor in context. Here is how the programs differ, when each is the stronger choice, and what selective colleges actually evaluate on your transcript.
Ivy League schools read the full IB Diploma as maximum rigor, and competitive candidates typically carry predicted scores of 40 and above. Here is how to choose Higher Levels, manage predictions, and turn the Extended Essay into application material.
Harvard admits under 4 percent of applicants and sets no AP minimum. Oriel Admissions breaks down how many AP classes competitive Harvard applicants actually take, how rigor is read in context, and which subjects matter most.
Cornell admits 6.9 percent of applicants across eight undergraduate colleges with different rigor expectations. Here is how many AP classes competitive Cornell applicants take and how the right mix changes by college.
Dartmouth admits 5.8 percent of applicants and explicitly reads for depth over volume. Here is how many AP classes competitive Dartmouth applicants take, why quality beats count, and how limited school offerings are evaluated.
Brown admits 5.35 percent of applicants, and its open curriculum raises rather than lowers rigor expectations. Here is how many AP classes competitive Brown applicants take and how PLME changes the calculation.
MIT sets no AP requirement, but calculus and physics preparation is effectively non negotiable. Here is how many AP classes competitive MIT applicants take, which STEM subjects form the real floor, and how context changes the answer.
Penn admits 4.1 percent of applicants and reads transcripts by undergraduate school. Here is how many AP classes competitive applicants take for Wharton, Penn Engineering, and the College, and which subjects each school expects.
Columbia admits 4.23 percent of applicants and its Core Curriculum changes what a strong transcript looks like. Here is how many AP classes competitive Columbia applicants take and why humanities rigor matters even for engineers.
Princeton admits 3.9 percent of applicants and sets no AP minimum, but B.S.E. and A.B. candidates are read differently. Here is how many AP classes competitive Princeton applicants take and which subjects each degree path expects.
Stanford admits roughly 3.6 percent of applicants and publishes no AP minimum. Here is how many AP classes competitive Stanford applicants take, how intellectual vitality shapes the read, and why REA timing changes your AP plan.
