Sadlier-Oxford is famous for several different learning materials and books. The most famous one is called Sadlier-Oxford Vocabulary Workshop new and old edition that are used in most schools in US as well as abroad. There are no detailed statistics on how many schools uses vocabulary workshop books but we can be sure that most schools does.
Sadlier-Oxford vocabulary workshop series books are well designed and covers all the main vocabulary related questions and exercises. If you can get through all these books you are master of vocabulary and you can feel confident at your level of knowledge.
I have gone through all 8 vocabulary workshop levels and I can assure that it doesn't come easy especially these reviews units that are usually checked by teacher. I have never failed in these but I have been very close to it. While these exercises might seem hard it is better to learn all of them because you will need them in life. It is not like math, chemistry, physics or some other sciences that you can easily skip and won't notice. You will use vocabulary for the rest of your life and if you will start cheating in early years you will find it very difficult to get a job or stick in your job because ideal vocabulary is the key.
I regret my decision what I cheated a lot in vocabulary workshop and now I pays back. My vocabulary sucks and it is hard to learn when you are not sixteen anymore. While I strongly recommend to avoid cheating by all means I can recommend this one website that helped me allow in school and most likely it will help you get going as well.
This website is created by lazy students just like me and you and it covers all Sadlier-Oxford vocabulary answers from Level A all way up to Level H. However, these answers might be innacurate and should be checked at least twice before you hand them in.
The safest strategy is to do your own homework and then check how well you performed so you avoid any problems you might have. This will dramatically improve your grades and knowledge because you are not cheating you are just checking your answers.
Use these vocabulary workshop answers wisely and please, please learn something on your own so you don't end up stupid because vocabulary really matters.
