Core Subject Review

Math

Mastery of numbers, conversions, proportions, and dosage calculations is vital. In nursing, miscalculations can lead to serious errors.

Key Math Topics

• Fractions ↔ Decimals ↔ Percentages conversions
• Ratio and proportion problems, dosage calculations
• Unit conversions (kg ↔ g ↔ mg, L ↔ mL, tsp/tbsp ↔ mL, etc.)
• Word problems that combine multiple steps (e.g. convert unit, calculate dosage, compare rates)

Conversion Reference Table

Dosage Calculation Formula

Use the proportion method for safe dosage calculation:
$$\frac{D}{H} = \frac{X}{V}$$
Where:

• $D$ = Desired dose
• $H$ = Dose on hand (per unit)
• $X$ = Amount you give
• $V$ = Volume or unit of available dose

Example: If you have 250 mg tablets (H) but patient needs 500 mg (D), then
$$\frac{500}{250} = \frac{X}{1 \text{ tablet}} \implies X = 2 \text{ tablets}$$

Study Math Effectively

• Begin each study session with a quick daily warmup on AccelePrep
• Write out and memorize common conversion tables
• Practice 5–10 dosage/ratio problems daily — variety builds speed and accuracy
• After each problem check your work carefully, especially units. Use missed-question review to understand errors

Reading Comprehension

Reading comprehension builds skills you’ll use continuously — understanding patient charts, instructions, academic texts, documentation.

What to Focus On

• Identifying main idea and supporting details
• Drawing logical inferences from context
• Recognizing tone and author’s intent (inform, persuade, instruct)
• Managing time per passage — reading steadily without over-analyzing

Practice Tips

• Use AccelePrep to do daily warmup passages — build daily reading stamina
• After each passage, write 1–2 sentence summary to reinforce comprehension
• Practice inference questions regularly — these often test higher-order thinking, not just recall
• Try mixed-topic reading: medical passages, general passages, technical passages — broad exposure improves flexibility

Vocabulary & Medical Terminology

Clinical settings and nursing courses often use medical terms. A strong vocabulary helps you learn faster and interpret materials accurately.

Common Medical Terms

How to Learn Terminology

• Break words into prefix + root + suffix to decode meanings
• Use flashcards (digital or physical) — daily review helps with long-term retention
• Use vocabulary practice in daily warmups on AccelePrep — repeated exposure is key
• When reading science/medical passages, pause to identify and define unfamiliar terms

Grammar / Language Usage

Clear, correct communication is indispensable in healthcare — in patient charts, reports, documentation, academic work.

Core Grammar Concepts

Practice Strategy

• Integrate grammar exercises into your daily warmup routine
• After writing sentences (for any reason), revisit and proofread carefully — become habitually attentive to grammar
• Review mistakes from missed-question logs to spot recurring patterns — those are your “grammar weak points”

Biology

A strong biology foundation underpins anatomy, physiology, microbiology, and later coursework.

Core Topics

• Cell structure and organelles — functions and relevance to physiology
• Cell division (mitosis and meiosis) — basic genetics and reproduction
• Basics of genetics — inheritance patterns, dominant/recessive traits, genotype & phenotype
• Basic ecology and organism interactions (less emphasis, but sometimes included)

Study Approach

• Use AccelePrep to review cell diagrams, definitions, and organelle functions regularly
• Combine reading + drawing: sketch a cell and label organelles to reinforce visual and textual memory
• Use flashcards for genetics vocabulary (e.g. genotype, phenotype, homozygous, heterozygous)
• Test yourself periodically — use question banks and missed-question review to lock in correct understanding

Chemistry

Chemistry fundamentals support understanding of pharmacology, fluid balance, acid/base, and physiology.

Core Concepts

• States of matter, atomic structure, chemical bonding (ionic, covalent, polar)
• Balancing chemical equations — ensures matter conservation
• Molar mass and calculations — used for dosages or chemical preparations
• pH and acid/base basics — relevant for body fluid balance, medication, physiology

Key Reference Formulas / Concepts

• Balanced reaction example:
  $$2Na + Cl_2 \rightarrow 2NaCl$$
• Molar mass calculation: sum of atomic masses — essential when calculating doses or solutions
• pH formula:
  $$\mathrm{pH} = -\log [\mathrm{H^+}]$$
  Understand how [H⁺] concentration affects acidity/basicity

Study Strategy

• Create a “chemistry cheat sheet”: atomic weights, common ions, bonding types, formulas — review often
• Use AccelePrep flashcards and practice questions after studying each concept
• Build chemistry into daily or weekly revision — do not wait until later; regular small doses aid long-term retention
• Practice chemical equations, balancing, and simple molar mass problems until comfortable

Anatomy & Physiology

This is one of the most extensive and important content areas — understanding how the human body works is foundational for nursing.

Major Systems to Know

• Cardiovascular — circulation, heart function, cardiac output
• Respiratory — gas exchange, mechanisms of breathing, diffusion
• Digestive — food breakdown, nutrient absorption, organ functions
• Urinary — waste filtration, fluid balance, kidney function
• Nervous — control, communication, reflexes
• Endocrine — hormone regulation, feedback loops
• Musculoskeletal, Immune, Integumentary, etc. — basic structure and functions

Key Formula & Functional Understanding

• Cardiac Output:
  $$CO = HR \times SV$$
  Where HR = heart rate, SV = stroke volume. Useful in understanding hemodynamics and cardiovascular physiology
• Understand how systems interrelate — e.g. respiratory & cardiovascular systems working together to deliver oxygen

Study Recommendations

• Use AccelePrep’s question bank to test each system individually — then mixed system questions for integration practice
• Draw diagrams — body systems, flow charts, organ interactions — make visual memory strong
• Use spaced repetition: review each system more than once over weeks rather than cramming before test day
• After studying, use missed-question review to clarify misunderstandings — many anatomy/physiology errors come from confusion between systems

Study Schedule + Strategy

Here is a proposed 8-week plan (adjust to your exam date) combining content review + AccelePrep tools + active learning

Daily / Weekly Best Practices

• Use daily warmups — even short sessions build habit and retention
• After any practice or mock test, always review mistakes and write out why correct answers are correct
• Use flashcards and drawings for visual memory and active recall
• Mix topics instead of studying in blocks for long periods — mixing improves retention and prepares you for mixed test sections
• Stay consistent — progress builds over time; consistency beats last-minute cramming

Test-Day & Mindset Advice

• Treat the exam like a simulation: timed sections, minimal breaks, quiet environment
• Manage time well: pace yourself, do not linger too long on any single question
• Use elimination strategies: rule out obviously wrong answers first, then make best guess if unsure
• Read questions carefully — many mistakes come from misreading or misunderstanding wording
• Stay calm: use deep breathing if anxious, and remember you prepared with consistent effort via AccelePrep tools and this guide
