Query: Dime Uno is hard to understand

As a student in high school trying to use Dime Uno, I find that I cannot find any information about grammar, punctuation, or vocabulary without reading the entire chapter through. The cartoons would be better if the were not quite so frequent, as they are, they hinder learning. They only teach in the singular for the first unit,making it hard to learn the plural when it is taught. I would look for another textbook.
