This is an excellent text book, very concise, bags of good information and complimentary exercises . A little too much information for absolute beginners, you would need to have a basic understanding of verb usage to be able to benefit from it.
Love the aroma of these freshners when they are first put on the bag however they do lose their strength of aroma quite soon probably due to the efficiency of the sebo bags . They are good however and I will probably buy them again . The delivery was very prompt
