I bought this for a quick reference in my beginning Spanish class, it's comprehensive enough to refer to it quickly for anything to do with my homework, class activities and so forth. It's easy to use and I have bought these for French as well. I use it all the time, I highly recommend these for quick reminders or even quick lessons if you miss something.
I purchased this for a family member who is currently taking a Spanish class; they have found it to be quite useful. This is a six page, laminated, Quick Study Spanish Grammar information reference chart that includes...alphabet, prepositions, adjectives, verbs, nouns, adverbs, capitalization, syllabification, rules of stress and much more. It also has 3 holes already punched in the side so you can quickly add it to any binder. I would recommend this to anyone just starting to learn the Spanish language and who would like a quick and easy reference guide.
I bought this for my son to help him review for his high school required Spanish class. It contains a lot of useful information in a very compact space and its bright colors make studying at least a little pleasant.
