Cambodia Health Entrance Exam study plan

Cambodia Health Entrance Exam · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Biology & Chemistry

  • Build a one-page formula and definition sheet for cell structure, biomolecules, and atomic structure from a single textbook chapter each

  • Solve 40 multiple-choice biology items on cell organelles and transport, and log every wrong answer with the reason it was wrong

  • Solve 40 multiple-choice chemistry items on atomic number, isotopes, and electron configuration, targeting 80% accuracy

  • Draw and label a plant and animal cell from memory twice in the week without notes

  • Convert between moles, mass, and number of particles for 20 practice problems with units shown at every step

Your checkpoint

A dated error log with at least 30 corrected biology and chemistry items and a handwritten formula sheet covering weeks 1 topics

Week 2

Biology & Chemistry

  • Explain photosynthesis and cellular respiration from inputs to outputs in writing, naming each stage and its location

  • Balance 25 chemical equations, including 5 redox reactions, and identify the oxidizing and reducing agent in each

  • Solve 40 genetics items on Mendelian ratios, Punnett squares, and pedigree interpretation

  • Compute molarity, dilution, and percentage concentration for 20 solution problems

  • Recite the periodic table trends for atomic radius, ionization energy, and electronegativity across a period and down a group without notes

Your checkpoint

A closed-book 30-question mixed biology and chemistry quiz scored and reviewed, with every miss reworked on paper

Week 3

Biology & Chemistry

  • Map the human body systems (digestive, circulatory, respiratory, excretory, nervous) and state the function of each major organ

  • Predict products for 20 acid-base and precipitation reactions and write the net ionic equation for each

  • Solve 30 biology items on the cell cycle, mitosis versus meiosis, and DNA replication

  • Calculate pH for strong acid and strong base solutions and classify 15 given pH values as acidic, basic, or neutral

  • Summarize the classes of organic compounds (alkanes, alcohols, carboxylic acids, carbohydrates, proteins) with one example each

Your checkpoint

A two-page systems summary sheet plus a 20-reaction product-prediction worksheet, both self-graded with corrections in a different color

Week 4

Biology & Chemistry & Mathematics

  • Complete a timed 50-question biology and chemistry mock under exam conditions and record the score per subtopic

  • Re-teach the five weakest subtopics from the mock to an imaginary student in writing, one paragraph each

  • Solve 30 mathematics items on ratios, percentages, and unit conversions used in dosage and dilution contexts

  • Reduce every mock error to a one-line rule you can apply next time

  • Review the error log from weeks 1 to 3 and confirm each earlier mistake is now solvable cold

Your checkpoint

A scored mock exam report listing subtopic accuracy percentages and a prioritized list of the five subtopics to fix in weeks 5 and 6

Week 5

Physics & Mathematics

  • Solve 40 physics items on kinematics, Newton's laws, and work-energy, drawing a free-body diagram for every force problem

  • Solve 30 mathematics items on linear equations, simultaneous equations, and quadratic equations without a calculator

  • State and apply Ohm's law and the power formulas to 20 circuit problems, including series and parallel combinations

  • Compute areas, volumes, and surface areas of common solids for 15 applied problems

  • Write out the SI units and dimensions for the 15 most common physical quantities used in the exam

Your checkpoint

A worked-problem notebook with 50 fully solved physics and mathematics problems showing the given, formula, substitution, and answer with units

Week 6

Physics & Mathematics

  • Solve 30 physics items on waves, optics, heat, and pressure, including 5 fluid-pressure problems in a medical or biological context

  • Solve 25 mathematics items on functions, graphs, and interpreting data from tables and charts

  • Perform 20 calculations involving density, specific heat, and heat transfer with unit checks

  • Solve 20 geometry and trigonometry problems relevant to angles and distances

  • Complete a timed 40-question physics and mathematics set and review every error the same day

Your checkpoint

A timed 40-question physics and mathematics set scored at 75% or better, with a correction sheet for all misses

Week 7

Biology & Chemistry & Physics & Mathematics & Logical Reasoning and General Aptitude

  • Run two full-length timed mocks across biology, chemistry, physics, and mathematics and record the score for each domain

  • Solve 30 logical reasoning items on sequences, syllogisms, and pattern completion, noting the rule type used for each

  • Review the top 20 recurring errors across all mocks and rewrite each as a flashcard

  • Practice 20 general aptitude items on data interpretation and basic arithmetic reasoning under a time limit

  • Compare domain scores against the exam weighting and reallocate remaining study time to the weakest weighted domain

Your checkpoint

A two-mock comparison table showing domain accuracy and total score, with a written plan for the final week

Week 8

Biology & Chemistry & Physics & Mathematics & Logical Reasoning and General Aptitude & Khmer Literature and General Knowledge

  • Review the condensed formula and definition sheets for all four science and mathematics domains once per day

  • Take one final full-length timed mock and score it under exam conditions

  • Recite key Khmer literature facts, authors, and works from your own summary notes for 30 minutes daily

  • Review general knowledge notes on Cambodian geography, history, and institutions for 20 minutes daily

  • Re-solve every flashcard marked wrong in week 7 until each is answered correctly twice in a row

Your checkpoint

A final mock score at or above your target, plus a one-page exam-day checklist covering timing strategy per section and materials to bring
