All around helpful---worth the money!
Format: Paperback
This guide has been most helpful for all the folks I help prepare for the iTEP test! It gives insight into what each section of the test is looking for along with examples and great tips about actually TAKING the test. In the Writing and Speaking sections, it also gives sample scores and comments from the Master Grader which is very helpful too.

Comprehensive, clear and coherent!
Format: Paperback
The iTEP Practice Guide combines a no-nonsense approach to the specific iTEP tests and at the same time offers exercises that task the student with what they need to know. Exercises not only serve the purpose of scoring well, but the overall approach is communicative competence. We use the text in our group and one-to-one classes with very positive--and lasting--results.

No recomiendo
Format: Paperback
Muy malo, no vine completo, además se demoró mucho más de lo que decía al momento de comprarlo. Solo aplazaban la fecha de entrega sin consultar cómo afectaba al cliente. Yo tuve que presentar el examen sin el libro, porque no llegó en la fecha que decía al comprarlo y después se cambió 3 veces la fecha, casi cumpliendo el mes.

Solid book that gives you useful commands and some Blue Team essentials
Format: Paperback
If you're looking at this, you know why you're looking at it, so not going to explain.
It is good. 130 or so pages and most of it is commands that are useful for your run books. The book doesn't explain how to interpret the results, but if you can understand it and are comfortable on a shell, you can probably hazard a guess anyways, or Google it.
A small amount of the commands are a tiny bit dated, which is expected with a print manual giving you commands for applications/OSes that are always changing, but even if dated, they at least give you the idea of what to run. Just go look up a good replacement application, or check the --help file for updated syntax.
Really liked the IR checklist at the back, will incorporate some of that.
