22 multiple-choice questions, written entirely in Spanish like the real exam, on Language and Culture: dialects, linguistics, customs, and exam format. Each has a full explanation of why every option is right or wrong.
Don't treat dialect vocabulary as an error. Regional words and voseo forms are correct Spanish: listening passages will test whether you can follow them, not "fix" them.
Sort culture into the 3 P's. When a question describes a custom or celebration, decide whether it's asking about the product, the practice, or the perspective: that usually points to the answer.
Watch for language-contact vocabulary. Terms like préstamo, spanglish, and bilingüismo appear often when a source discusses how Spanish and English (or Spanish and indigenous languages) interact.
Read the explanations even when you're right. Each one reinforces a fact or vocabulary word that often returns in a different form on the exam.
