B3 Biological molecules: vocabulary trainer
Practise 26 words by typing them: the 14 words of the unit and 12 general science words (compound, dissolve, reagent). Questions give a definition, a sound or an example sentence; words you miss come back, words you know come back later.
Clicking an answer is easy, but remembering a word means recalling it yourself. In this trainer you type the English word, with the right spelling, and you can hear every word.
The video teaches the 14 words of the unit. This practice has 26 words: the same 14, plus 12 general science words that appear in every IGCSE exam question. Words you get wrong come back in the same practice until you get them right twice. Words you get right come back after 1 day, 3 days, 7 days and 14 days, so they stay in your memory.
