I've recently removed the search bar from this blog. The reason I did this is that Google does much better searches that the blog's search bar did. Have you ever used Google to search this website?
Here's how to search this blog using Google:
1) First, search for "ielts simon" on Google.
2) You should then see the result in the image below.
3) Now use the "ielts simon" search bar circled in red above.
4) Google will give you results from this website only.
I use this option all the time to find old lessons on my blog. It's a great way to search for a particular topic, type of question, or anything else that you're worried about. For example, if you want to know about using capital letters in the listening test, just type "listening capital letters" into the search bar, and see what you find.
