A problem book and commentary for IT Passport exam preparation. - Title: IT Passport - Type: Problem book - Contents: Mini-test questions & answer explanations - Contents: Training problem book - Contents: Pass text & examples - Publisher: Ohara - Included materials: Additional materials Except for the training problem book, everything is unopened. The training problem book is also in good condition with no writing. I think it's a great deal, as it's expensive material from a correspondence course. Thank you for looking.
