NEW USERS, PLEASE - ENSURE THAT YOUR INTERNET BROWSER DOES NOT HAVE ITS 'SECURITY' SETTINGS SET TOO HIGH as the 'multichoice exercises' work as 'pop-up screens'- If you cannot 'see' multiple choice exercises when you click on them and instead 'see' a 'list of files' then you need to reduce the security settings in Internet Explorer. In IE, click on 'tools' from the 'drop down menus' at the top of the page. Then select 'Internet options' then click on the 'security' tab. You need to reduce the security to medium or below.

'FREE' SELF-MARKING MULTICHOICE EXERCISES SECTION

Each LEVEL, UNIT and related OUTCOME is shown below. Click on the TOPIC and the SELECTED exercise will load into a new 'window'. Simply close the new window when the exercise has been completed, leaving this window for you to make further selections from. YOU MUST ENSURE THAT YOUR INTERNET EXPLORER 'SECURITY' SETTINGS ARE NOT SET TOO HIGH - OR THE EXERCISE WONT LOAD. THERE HAVE BEEN SOME ISSUES WITH INTERNET EXPLORER 7 + 'firewalls' used by some colleges (mine included). I have recoded the exercises so they will work in IE7 - indicated by 'NEW' next to these updated exercises. I WILL CONTINUE TO UPDATE ALL MULTICHOICE EXERCISES so that 'firewalls' and 'virus checkers' will allow the exercises to open.

Click on ANY of the 'FREE' exercises below. The exercise will open in a new window with a selection of questions for that topic. Check the top of each COMPLETED and CORRECTLY answered exercise for your SCORE before closing the exercise window which will return you to this page. Each time any exercise is opened again, the questions are re-ordered along with the answers - so you will never see the same exercise twice!
