First I thought, that the example sentences wouldn't have such a big impact on the learning progress, but when I realized that I started placing adverbs and pronouns in the right position just after having studied some phrases before, I knew that was effective.

Your courses seem to be the perfect middle ground in-between saying a few cursory words, and really going for greater fluency with Glossika being my presence for that. 

I have learned German for more than a year but mainly enriching my passive vocabulary (with Assimil and LingQ). After using VocaBooster, I have the feeling I will finally feel more comfortable in speaking.
