When you are preparing for an exam such as IELTS or TOEFL one of the skills you need is to be able to read quickly the passages which you have to work on. Eyercize is a web-based tool which can help you do that almost unconcsciously. The site has a library of texts which you can practice your speed reading skills on but the really useful feature is the bookmarklet which means that you can mark any text on a website and turn it into a speed reading exercise. This means that you can get a great deal of practice quite easily simply from visiting the webpages that you are reading anyway.
The tool is also good for other languages and will cope with accents and other special characters in for example, French.
The trick to improving your reading speed is to increase the speed for two minutes or so and then revert to your original speed which will then feel quite slow in comparison.
