JackSparrow MCAT — MCAT Coverage Audit
The JackSparrow MCAT deck covers 404 of 408 subtopics in our MCAT content outline (99.0%) across 7,417 cards — the highest coverage rate of any single MCAT Anki deck we have audited. The JackSparrow MCAT deck is enough to build a strong content foundation on its own, but 4 subtopics have zero cards and 41 more are thin (1-3 cards), so targeted supplementation still pays off. This audit maps all 7,417 cards to the official MCAT content outline so you know exactly where the deck holds up and where it doesn't.
JackSparrow is a community-built Anki deck designed for MCAT prep. It skews heavily toward the sciences: Bioenergetics and Metabolism is the standout with 1,658 cards across all 19 subtopics (100% coverage), Gene Expression leads volume at 1,521 cards across 16/16 subtopics, and Proteins and Amino Acids achieves perfect coverage with 681 cards. Cell Division hits 100% across all 9 subtopics with 1,326 cards. These are the highest-yield biochemistry and biology areas on the MCAT, and JackSparrow dominates them with card counts that dwarf competing decks (AnKing covers Bioenergetics with 653 cards; JackSparrow has 1,658). The deck is best suited for students who want deep science coverage and are comfortable supplementing a few narrow gaps independently.
The weaknesses are narrow. Cognition, Learning, Memory, and Language misses 1 of 19 subtopics (States of Consciousness Overview) despite having 1,765 cards. Heredity and Genetic Variation covers 10 of 11 subtopics, with Pedigree Analysis and Modes of Inheritance completely absent (0 cards). Water and Solutions covers 9 of 10 subtopics, missing Water — Polarity, Hydrogen Bonding, Anomalous Density entirely. Prokaryotes and Viruses covers 8 of 9 subtopics with only 27 cards total — the thinnest section in the entire deck relative to MCAT weight, missing Bacterial Growth Curve and Binary Fission entirely. This page is the only independent per-subtopic audit of the JackSparrow MCAT deck against Lacunos's 408-subtopic MCAT content outline. Use the gap data below to build your supplementation plan.

How to pair JackSparrow MCAT with other resources
JackSparrow's 4 zero-card gaps and 41 thin spots concentrate in a few predictable areas, so targeted supplementation closes them faster than adding a second deck. For Pedigree Analysis and Modes of Inheritance — a zero-card gap in a high-yield genetics topic — Khan Academy's genetics unit is the fastest fix: watch the pedigree and inheritance videos, then make a handful of custom Anki cards. The missing Water — Polarity, Hydrogen Bonding, Anomalous Density subtopic is best covered with a Kaplan content book chapter review, since the concept requires diagram-based understanding that flashcards alone handle poorly. For the 27-card Prokaryotes and Viruses section — dangerously thin given MCAT weight — Khan Academy's microbiology unit fills the missing Bacterial Growth subtopic and deepens the 7 thin subtopics that average fewer than 4 cards each.
For Psychology and Sociology, JackSparrow delivers strong numbers — Social Inequality and Health Disparities hits 100% coverage with 693 cards, and Social Structure covers all 18/18 subtopics with 1,094 cards — but the 300-page KA P/S document is still essential alongside it. The 300-page doc provides the psychological theory framing that pure flashcard review misses, especially for Cognition, Learning, Memory, and Language where States of Consciousness Overview has zero cards. Use JackSparrow for daily Anki review, Kaplan for visual and conceptual reinforcement in gap areas, and the 300-page P/S doc as a reading pass before locking in your psychology cards.
Frequently asked questions
Is JackSparrow enough for MCAT?
JackSparrow covers 404 of 408 subtopics in our MCAT content outline (99.0%) across 7,417 cards — the highest coverage rate of any single MCAT Anki deck. Four subtopics have zero cards (Pedigree Analysis, Water Polarity/Hydrogen Bonding, States of Consciousness, Bacterial Growth) and 41 more are thin at 1-3 cards. Pairing it with Khan Academy and the 300-page KA P/S doc closes those gaps.
How many cards are in JackSparrow?
The JackSparrow MCAT Anki deck contains 7,417 total cards, of which 7,203 map directly to official MCAT exam subtopics with zero out-of-scope cards. The largest sections are Nervous and Endocrine Systems (2,072 cards), Sensation and Perception (1,997 cards), and Cognition (1,765 cards).
What does JackSparrow not cover for MCAT?
JackSparrow has 4 zero-card gaps: Pedigree Analysis and Modes of Inheritance (high-yield, Heredity), Water Polarity/Hydrogen Bonding (high-yield, Water and Solutions), States of Consciousness Overview (Cognition), and Bacterial Growth Curve (Prokaryotes). An additional 41 subtopics are thin at 1-3 cards, with Prokaryotes and Viruses the thinnest section at 27 cards across 8 of 9 subtopics.
What is the weakest section in the JackSparrow MCAT deck?
Prokaryotes and Viruses is the weakest section — 8 of 9 subtopics covered but only 27 total cards, far below the card density of other biology sections. Heredity and Genetic Variation (10/11 subtopics, 90.9%, 104 cards) is the second weakest by coverage rate, with a critical zero-card gap in Pedigree Analysis. Both areas warrant direct supplementation before test day.
