For most students already preparing seriously for AIME qualification, attempting both AMC 10A/12A (November 5, 2026) and AMC 10B/12B (November 13, 2026) is worth it, since only the better of the two scores counts and the eight-day gap this cycle is enough for a short, targeted review. It's not automatically the right call for every student, though โ€” a student who isn't genuinely exam-ready for the first sitting usually gains more from one well-prepared attempt than two rushed ones.

This Cycle's Exact Gap: Eight Days, Not Two Weeks

The gap between the A and B papers isn't fixed year to year โ€” it depends on where the MAA schedules each sitting. This cycle, it's tighter than usual: AMC 10A/12A on November 5, 2026, and AMC 10B/12B on November 13, eight days later, a Friday-to-Friday turnaround. That's meaningfully less time than a two-week gap would give, which changes how the days in between should be spent. For a general breakdown of what actually differs between an A and a B paper in content and difficulty, AMC 10A vs AMC 10B covers that; this piece is about the specific decision of sitting both this cycle.

The Registration Logistics of Sitting Both

Each sitting is a separate registration through a test center, and centers can have different availability for the A and B dates โ€” it's worth confirming both slots are actually open at the same center before assuming a second attempt is simply a formality. Booking both now, rather than deciding after seeing how November 5 goes, avoids the scramble of trying to secure a B-paper seat with only a week's notice, when a center's capacity for that date may already be committed.

How to Use the Eight Days Between November 5 and 13

Eight days is enough for a focused review, not a second full preparation cycle. The most productive use of that window is a same-day or next-day error review of the November 5 paper โ€” going through every missed or guessed question and sorting mistakes into genuine content gaps versus careless errors versus time-pressure decisions. Content gaps get two or three days of targeted work; careless-error patterns get addressed through slower, more deliberate practice on a handful of problems rather than volume; and time-pressure issues get addressed with one more timed set in the final two or three days, not several.

  • Days 1-2 after November 5: thorough review of the paper just sat โ€” every wrong or guessed answer categorized by cause, not just marked right or wrong.
  • Days 3-5: targeted work on the two or three specific gaps that review surfaced โ€” not a broad re-review of the entire syllabus, which the timeframe doesn't really allow.
  • Days 6-7: one timed practice set, at real exam pace, to rebuild pacing instincts without adding fresh fatigue right before the second sitting.
  • Day 8 (exam day): treat it like exam day, not a rematch to prove something โ€” the score that counts is whichever of the two is higher, so there's no benefit to over-pressuring the second attempt.

When Attempting Both Is Not the Right Call

Sitting both makes the most sense for a student who is already reasonably exam-ready for November 5 and simply wants a second, lower-stakes shot at a better score. It makes less sense for a student who isn't there yet โ€” cramming toward a rushed November 5 attempt just to 'get a look at the format,' then trying to fix everything in eight days before November 13, usually produces two underprepared scores instead of one solid one. In that situation, it's often better to register for only the B paper, use the extra eight days for real preparation, and sit one genuinely ready attempt rather than two anxious ones. School commitments, travel, or a test center only offering one of the two dates are equally valid reasons to attempt just one.

Common Mistakes to Avoid

  • Assuming the second attempt is a free do-over with no real preparation needed. The eight days between sittings are short but genuinely useful if spent on targeted review โ€” wasting them assumes the second score will simply be better by default.
  • Registering for the B paper only after seeing how the A paper goes. By then, seats at a preferred center may no longer be available.
  • Treating the review week as a repeat of full-syllabus revision. Eight days isn't enough time for that; a narrow focus on the specific gaps the first paper revealed is what actually helps.
  • Piling on stress for the second sitting by treating it as a must-beat rematch, when in fact only the better of the two scores counts and there's genuinely nothing to lose by attempting it calmly.

Expert Tips from BuzzyBrains Academy Faculty

Founder Dilip Sah (IIT Kanpur alumnus, JEE AIR 400, 25+ years of mentoring experience) plans the eight-day window between this cycle's two sittings as a deliberate part of the prep calendar, not an afterthought:

  • A same-day error review is scheduled right after the November 5 paper, so the eight days are used for targeted correction rather than lost to a post-exam lull.
  • Students who aren't genuinely exam-ready for November 5 are advised honestly on whether a single, better-prepared B-paper attempt makes more sense than two rushed sittings.
  • Small batches (max 12 students) at the Amanora, Hadapsar centre, with an online option, allow this kind of individualized eight-day review plan for each student rather than one generic revision sheet for the whole batch.
