Make flash cards for learning vocabulary in each chapter, writing the English meaning on one side and the Spanish meaning on the other. In lieu of flash cards, make a list of vocabulary words in English and then translate to Spanish from memory. It it more difficult to translate from English to Spanish, so it is best to get into the practice early on. Those vocab tests will seem much easier. Accent marks - if words include accent marks, be sure and include them in practice and on tests.
Accent marks can change the meaning of a word drastically.
By learning accent marks with vocabulary early on, you will be able to comprehend readings quicker and be able to write what you intend to convey. Listening exercises - take them seriously. If you want to advance in Spanish or if you are preparing to teach Spanish, the listening portion of learning is essential. Exams at the Intermediate level include a listening section, and the National Teachers Exam for Spanish does as well. Make up a practice test as soon as you find out what the exam will cover.
