  2. maria says:

    oh the vocabularies are great to know… can an essay format be? how many paragraphs shall it be?

    Hi Pearl
    Thank you so much for your posts. They are very helpful. I’m having problems in reading. I manage to get a 7.5 , which I’m not satisfied with. I make mistakes usually in the task assigning headings or what the paragraph is about ( with options). I end up giving the wrong labels due to subtle difference in the meanings. How do I work on this and get an 8 ? Otherwise I get an 8.5 in listening and I believe my speaking is good. I practice at home.

      Hi Monikha,

      Thanks for your comment. I’m glad you find them helpful. As for your question, I think you’re on your way to working this out. At least you’ve identified where you are making your mistakes in the specific type of question. I would then go through all your practice tests and find out where you’ve made that mistake and more importantly why. How are the meanings of the two choices you are faced with different? What exactly is the subtle difference between those answer choices? Did you choose just a detail for a paragraph, rather than a main idea of the paragraph? If you can find a pattern in your mistakes, that can lead you to correcting it.

      A more general strategy is to just read more English materials – blogs, newspapers, magazine articles. You broaden your recognition and understanding of vocabulary and how it is used in different contexts. You also become more familiar with more topics as explained in English, which can help you in the reading tests as you can sometimes connect your background knowledge to the reading passage in the exam.

      It’s hard for me to pinpoint what it is exactly, but I hope that helps somewhat.Good luck in your studies!

      Cheers, Pearl

        Hi Pearl
        Thank you for your tips. Yes, as you said in the previous post, I tend to look at some detail and not the main idea. So, when the same detail is giving in two paragraphs, I make the labeling based on the detail and miss out on a main idea they are talking about.

  4. Leonte Dan says:

    Is it correct to say : They remained stable at 15 percent ? I mean, the preposition
    ,,at ,,is used correctly or there should be another preposition instead?

  5. Leonte Dan says:

    Thankyou very much, Mr. Pearl.
