Revision
Hints
Note
- in the exam you will be provided with a Periodic table and a table
of Ions and their charges.
The best preparation for exams is to listen, take notes, and do
exercises well in class and to do your homework thoroughly. You
should answer each homework question as if it is an exam question.
This extra and consistent work put in during the term will help
you to achieve well and reduce the amount of work needed at the
end of term. It will also establish good study habits that will
pay dividends in Year 12 results and university.
