and miscellaneous selection of word-fill quizzes and crossword puzzles

I hope all these self-assessment quizzes and work sheets will prove useful, whatever course you are doing. Scroll down to see what's on offer and F/H means differentiation for UK GCSE/IGCSE foundation/higher level tier quizzes (it basically means easier on limited knowledge and harder on wider ranging questions).

The 10 m/c Q's selected at random from a database of 50-250 Questions. When doing the KS4-GCSE-IGCSE multiple choice science-chemistry calculation quizzes, if you get the answer correct, a YES comes up in the box by the choices A-D. If you get it wrong, a NO appears.

However, if your first three answers are incorrect, on the 4th click, which is the answer, nothing appears! This I'm afraid is peculiar quirk, in the otherwise excellent free to use Hot Potato download software I use.
