Hey, you can always try teaching yourself or reading the textbook independently to understand the language better. If not, you can try free websites that help you learn.
Duolingo, Memrise, http://study.com/academy/course/spanish.html, onlinefreespanish.com, quizlet, etc.
These would be helpful to study for about 30 minutes to an hour per day, but you need to maintain the rehearsal of memorizing the phrases and vocabulary words so that it won’t fade away.
I hope this helps.
