The CHEM 3A Course Bundle — original practice exams & exam DNA
O-chem: the memory-load monster.
Mechanisms and stereochemistry — converted into decision rules.
Course Bundle — the full rehearsal system
Exam DNA, mock exams, sprint, protocol, and the recall deck — everything for this course in one checkout.
Exam DNA
The course's real question patterns, decoded.
Mock Exam
Real format, rubric-style solution key.
Sprint
Day-by-day plan keyed to the term calendar.
AI Protocol
Use AI tutors without trusting unverified answers.
Recall Deck
180 original cards · 10 topics · Anki-importable + printable.
Why this course hurts
CHEM 3A doesn't lack effort. It lacks a system.
- Hundreds of reactions, and one wrong reagent erases the whole answer.
- Stereochemistry (R/S, E/Z) haunts every single question.
- SN1/SN2/E1/E2 decisions feel like coin flips until you get the rules.
- One arrow-pushing mistake propagates through an entire mechanism.
What's in the Course Bundle
Five products. Each one earns points.
Exam DNA Report
The archetype map for 3A exams: SN1/SN2/E1/E2 decision questions, stereochemistry traps, mechanism prediction, and spectroscopy identification.
Mock Exam Pack
Two original full-length mocks in the 3A format — mechanism walkthroughs with full arrow-pushing, plus rubric-style partial-credit keys.
14-Day Exam Sprint
A day-by-day plan: one reaction family or decision rule drilled per day — mechanisms decay without spacing.
AI Study Protocol
AI draws plausible-but-wrong mechanisms: prompts for practice generation, plus the arrow-check verification routine.
Recall Deck
180 cards: reagent decision inputs, stereo rules, and diagnostic patterns. Anki-importable and printable.
The trap list
What actually sinks CHEM 3A students
- 1
Naming the product right and drawing its stereochemistry wrong.
- 2
Memorizing reagent pairs instead of decision inputs.
- 3
Ignoring rearrangements when a more stable carbocation exists.
- 4
Half-learning spectroscopy patterns — “that one NMR shift” that decides the question.
Look inside
A spread from the Exam DNA
Every Exam DNA follows this layout: the recall schedule you'll run, the high-yield concepts explained as decision rules, the traps called out before they cost you points, and practice designed to be done from memory.

The CHEM 3A Recall Deck
- 180 original cards across 10 topic clusters — concepts, decision rules, and worked-question prompts.
- Anki-importable TXT/CSV files + a printable PDF version for paper reviewers.
- Built for spaced repetition — card order and tags follow the sprint's recall plan.
- 3-minute import guide included (Anki and Quizlet).
CHEM 3A FAQ
Is this specific to how the course is actually taught?
The DNA report covers the course's stable core — the exam archetypes, the point economy, the decision rules. For professor-specific details it routes you to the course's own public materials (mapped in the Free Stack section of your DNA Report), and the Sprint adapts in minutes.
Which products do I actually need?
The DNA report tells you what the exam asks; the mock pack makes you rehearse it; the deck makes it permanent. Most students take the Course Bundle — all five products are $56 separately, and the bundle is $39 — the whole course for the price of the Mock Exam Pack plus $20.
How do I import the deck?
Any flashcard app that imports text (Anki, Quizlet). Each deck ships as Anki-importable TXT/CSV plus a printable PDF, with a 3-minute import guide included.
What if it doesn't help?
14-day refund, no questions asked. We'd rather refund you than keep a dollar that didn't earn itself.
