Test yourself in microelectronics, science & maths.
Click here for updates.
These pages contain programs I am developing in HTML and javascript to consolidate skills in Science - Chemistry(up to GCSE), Physics(GCSE, A-level & medical), Biology(up to GCSE) electronics (up to A-level) and maths. They include calculations and writing and balancing chemical equations. They use 'Drag and Drop' (DnD) techniques, show/hide sections, and DOM.
Any ideas/suggestions, please email
me. The list of areas covered is in above menu (mouseover to expand the lists).
These are mainly drill exercises. They do not profess to teach the principles - they are taught in the classroom and on websites such as www.paulgardiner.co.uk (electronics) and mathisfun.
Programs were initially written for MSIE6. They are now written primarily for MSIE7. To check compatibility with other browsers: click

Change of Name
I am now hosting the website with carbootsRus
This website lists details of car boots by area and has over 3000 carboot locations in the data base.
This website has a free domain forwarding name from dotTK - www.testYourself.tk
This is still active but may not offer the full facilities of testYourself.org.uk

This website takes a fair bit of time to keep running. To help support the website: if you would normally use any of the advertisers opposite, please click via this site. The price to you is the same and a small commission goes to help out. Thank-you.
Pop-ups
Many programs have 'help' pop-ups. To benefit, you need to allow pop-ups. They may show the equation given in the specification or give some other help.
There are no ads on the calculation pages. So no ads should popup, or, popunder.
The pop-ups close as soon as they lose focus. Two reasons: to encourage you, the student, to keep the idea in your head and, also, new pages would appear in these small windows.
Browsers
Programs are initially written for MSIE6/7 set to 'Medium' Text-Size. To check compatibility with other browsers: click here. Programs using DnD are most difficult to get compatible with other browsers, including IE7. If you want to use a particular program and are finding difficulties with your browser, please let me know and I will try to help. I don't have access to Mac or Apple computers so am unable to check compatibility.
Disclaimer
Before IE7, I wrote the programs for IE6.
Most were then tested in other browsers. Since May, however, all programs are written for IE7. In addition, programs are occasionally updated in IE7 to take advantage of improved techniques. I have not yet been able to check all the older programs for compatibility with IE7. Also, I have not always had time to check changes in other browsers.
Teachers Please check any program before using it with a class especially if you are using another browser as programs are subject to alterations in script which may affect working in other browsers. Programs using DnD are particularly at risk here!
Settings:
I have written a comprehensive list of settings you can use to help you get the best from this website.
Cookies:
To benefit from the 'Personal Best Score' (PBS) programs you need to enable cookies.
Javascript
All programs use javascript for the calculations. To use the programs at all, javascript must be enabled.
Screen Resolution:
Best viewed at as high a resolution as possible. Minimum 1024 x 768 advised. 800 x 600 is usually inadequate.
Full screen (press <F11>) is useful. (press <F11> to exit).
Recent Additions & Updates 2009-10
5 January 2010: Engineering Notation and Percentages recoded to allow scores to be recorded on Server. Thus, exercises set for homework are marked and teachers can retrieve the marks to check homework attempted. Please email for details. This service is free to teachers emailing from a school email address.
1
6 November: Percentages eliminating most of the popups and tick / X images to mark your answer.
9 November 2009: BIDMAS calculations (Maths), Engineering Notation examples (Electronics)
5 November 2009: Percentages (Maths)
30
October 2009: Sums with fractions(Add, subtract, multiply and divide) - see Maths Menu above. Script only allows numerical input.
Apr 27 2008: Setting up a Departmental domain? Want to use Server 2003?
I have written a script to upload students from an Excel Spreadsheet into Active Directory. All you need to enter in Excel are: First and Second Names, Year of entry to school and Departmental Teaching Group. It provides a unique logon name (format <entry year><surname><unique id if necessary>), and an initial, randomised password which can be displayed by projector.
It organises by Year Group.
It reads the Teaching Group and enters students into these groups in AD and also sets up a home folder for each student.
You can edit the spreadsheet at any time and rerun the script. It will resort the students in AD and their home folders into any new teaching groups so you don't lose any of their work. Ideal for the new school year.
Email me
for more details - the script and sample SpreadSheet are free.
Jan 20: Worked out how to allow only decimal number entry to input text boxes ie: numerals 0-9 and only one decimal point and forcing a leading 0 if < 1. The coding allows for deletions of any of the digits and / or '.'. Starting to edit programs starting with 'density'.
Jan 6 2008: Calculators for 3 variable calculations -
Density
Speed
.
Useful for Y6 - Y9 when students seem randomly to use calculators to calculate e.g. density as mass/volume and volume/mass! Of course, students can put all the information into a class spreadsheet. However, I have found these calculators useful as aids to confirm their own calculations. Answers are shown to 3 sig figs.
For the IE7 version, all keys except 0-9 & '.' are disabled. Non-numbers are also captured.
If you would like any similar calculator produced, please let me know and I will add it to this site.
June 5: change hosting service and address
May 18: 555 Monostable calculation
Feb 7: audible.co.uk link for mp3 revision.
Dec 24: medical physics CT scan & backprojection
Dec 3: always on top, moveable, 'popup' calculator for 555 timer
Dec 1: acid + carbonate DnD equations.
Nov 28: New menu now compatible with IE7 and added to chemical equations pages. Now easier to navigate between equations. Starting to add double decomposition equations.
Nov
26: Expanding menu updateable from separate file. Compatible with Mozilla.
