Misspelling key specification terms, causing marks to be lost even when knowledge is present
“spelling errors meant that a large number of candidates who knew the word did not gain the mark. Key specification terminology needs to be spelt correctly to achieve marks.”— 9PE0 Paper 1, June 2023
How to fix: Build a spelling list for every topic: rectus abdominis (not 'abdominals'), sarcomere, myosin, tropomyosin, troponin, creatine kinase, ATPase, vasoconstriction, vasodilation, bradycardia. Write the word out correctly three times after each revision session. In the exam, if you are unsure of a spelling, write the answer in a sentence — context sometimes secures credit even with a minor error — but aim for exact spelling.
