Easily a worthwhile investment for boosting your Spanish in all respects. Compared to the potential cost of learning this much through lessons I’d say the resources are a bargain.
I have used all the learning materials from Notes in Spanish and they’re the best ever at helping me learn to speak and understand Spanish. My absolute favorite is the Gold series because of the analysis that follows each conversation. It’s a wonderful way to review what you’ve just heard and clear up any questions you had as you were listening. I totally recommend all the Notes in Spanish audios and accompanying worksheets. They’ve made a huge difference in my Spanish! Thank you, Ben and Marina!!
