This is a grammar practice book for the TOEFL ITP. Please note that this is not a reference book for the IBT. It has been stored in a dark place after purchase. I have checked it and found no writing, but there may be oversights. Please understand. Although I have set it as new and unused, it has been in someone else's hands once. Please refrain from purchasing if you are nervous or seeking perfection. If you have any questions about the condition of the item or anything else, please feel free to ask. Thank you for reading this far.
