OAT study plan

OAT · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Survey of the Natural Sciences - Biology

  • Build a one-page cell-and-molecular-biology map covering organelles, membrane transport, and the central dogma, writing each process from memory before checking it

  • Define and contrast mitosis and meiosis stage by stage, listing the chromosome count and key event at each checkpoint

  • Solve 40 genetics problems (monohybrid, dihybrid, sex-linked, Hardy-Weinberg) and log every error with its cause

Your checkpoint

A 25-question self-written biology quiz on cells, division, and genetics scored at 80% or higher, with an error log of at least 10 entries

Week 2

Survey of the Natural Sciences - Biology

  • Diagram the major human organ systems and label the function of each organ relevant to gas exchange, circulation, digestion, and excretion

  • Explain the roles of the major hormones and trace the feedback loops that regulate blood glucose, water balance, and the menstrual cycle

  • Classify the major taxonomic groups and identify the distinguishing features of each

Your checkpoint

A hand-drawn physiology diagram set (at least 5 systems) with 30 labeled structures, self-tested by covering labels and reproducing them

Week 3

Survey of the Natural Sciences - General Chemistry

  • Calculate molarity, dilution, and stoichiometric yields for 30 problems without a formula sheet

  • Predict periodic trends in atomic radius, ionization energy, and electronegativity and justify each prediction in writing

  • Balance redox equations in acidic and basic solution and assign oxidation states correctly

  • Apply gas laws and the ideal gas equation to mixed problems involving partial pressure and molar mass

Your checkpoint

A formula sheet written from memory plus 50 completed general chemistry problems with at least 85% accuracy

Week 4

Survey of the Natural Sciences - Organic Chemistry

  • Name and draw alkanes, alkenes, alkynes, and aromatics using IUPAC rules, including stereochemistry notation

  • Predict products of substitution, elimination, addition, and oxidation reactions and identify the mechanism (SN1, SN2, E1, E2) from the substrate and conditions

  • Distinguish functional groups by their reactivity and describe how each appears in IR and NMR spectra

Your checkpoint

A 20-reaction synthesis map where each arrow is labeled with reagent, mechanism, and major product, checked against a textbook

Week 5

Physics

  • Solve kinematics and projectile-motion problems by selecting the correct equation and stating knowns and unknowns before calculating

  • Apply Newton's laws and conservation of energy and momentum to multi-step problems involving friction and collisions

  • Set up circuit problems using Ohm's law and series/parallel rules, and compute power dissipation

  • Describe wave properties, including frequency, wavelength, refraction, and the Doppler effect, with worked examples

Your checkpoint

A 40-problem physics set completed under timed conditions (60 minutes) with a written solution for every missed item

Week 6

Reading Comprehension & Physics

  • Practice the three reading question types (main idea, detail, inference) on 6 long passages, capping each passage at 8 minutes

  • Identify the sentence in each passage that supports the correct answer and note why each distractor fails

  • Finish remaining physics topics: optics, fluids, thermodynamics, and modern physics, with one worked example per concept

Your checkpoint

A reading log of 6 passages showing time per passage, score, and a one-line justification for every answer choice

Week 7

Quantitative Reasoning & Survey of the Natural Sciences - Biology

  • Solve quantitative comparison and data-interpretation items without a calculator, using estimation and backsolving

  • Convert between fractions, decimals, percentages, ratios, and scientific notation fluently across 30 drills

  • Re-review the two weakest biology subtopics from the week 1-2 error logs and rewrite those notes

Your checkpoint

A 30-question quantitative reasoning set completed in 45 minutes with at least 85% accuracy and no calculator use

Week 8

Survey of the Natural Sciences - Biology & Survey of the Natural Sciences - General Chemistry & Survey of the Natural Sciences - Organic Chemistry & Reading Comprehension & Physics & Quantitative Reasoning

  • Take two full-length timed practice exams and record section scores and pacing

  • Categorize every missed question by domain and concept, then rank the top five recurring gaps

  • Re-drill only the top five gaps with targeted problem sets and flashcard review

  • Finalize a one-page summary sheet per science domain for last-day review

Your checkpoint

A gap-analysis spreadsheet from two full exams listing every error by domain, with a remediation note for each of the top five gaps

Milestones

Week 2: Score 80% or higher on the self-written biology quiz and reproduce all 30 physiology labels from memory

Week 4: Complete the 50-problem general chemistry set at 85% accuracy and finish the 20-reaction organic synthesis map with correct reagents on at least 16 arrows

Week 6: Average 8 minutes or less per reading passage at 70% accuracy or better, and complete the timed 40-problem physics set

Week 8: Full-length practice exam scores improve by at least 10 percentile points from the first attempt, with no domain below 60%
