First of all, both of the tutors I had - Bladimir and Janeth - were excellent. Aside from knowing their stuff and able to clearly articulate the nuances of Spanish grammar, I thought they did a good job catering the classes to my needs (which not only were explicitly specified by myself but also determined in part by taking a diagnostic/placement exam they had me do even before arriving in Panama) and listening to and answering my numerous questions.
It also helped that they were both happy, kind, patient, and in general, people I would have loved to hang out and interact with even if I wasn't taking Spanish classes.
In addition to doing numerous exercises on confusing verb forms such as the imperfecto, subjuntivo, pluscuamperfecto, imperativo, etc., we also did trabalenguas (tongue twisters) to help improve my pronunciation and games such as Scrabble to keep my interest from waning.
One thing I particularly appreciated was that we spoke absolutely no English in class. Likewise, all reading material and written exercises were in Spanish. If I asked them what a word meant, they'd explain their meanings in español. In fact, I didn't even know that Janeth knew English and Bladimir did not until Tori (fellow classmate who also had them) told me, as I had not attempted to communicate with them in my native language at all or vice-versa.
I was particularly pleased that despite speaking exclusively in Spanish I could understand them 95% of the time. (Even Tori, who's somewhat less advanced in the language could generally get the gist of what they were saying in her classes.) I'm not sure whether they were talking slightly slower than they normally would, but it sure helped build a lot of confidence in my Spanish speaking and comprehension skills.
My opinion of the classes was high enough that I even wrote this testimonio for Carlos (a founder and the director of Habla Ya) for his promotional material. If there are any grammatical errors keep in mind I'm still at a intermediate-advanced level which will take far more than just seven days of classes to bring me to complete mastery, and that if it I had tried to write the following two weeks ago, it would have been much worse.
Me alegró mi experiencia con las clases de español de Habla Ya, ambos esos de grupo y las lecciones privadas. Mis maestros Bladimir y Janeth fueron excelentes. Ellos ayudaron aclarar mi confusión con varias formas de verbos rápidamente, y me encantaron los ejercicios y juegos de aprender que hicimos. Después de las clases, tuve más confianza en mi capacidad en conversar con otros en español. Habla Ya enseña un buen método para aprender español rápidamente y eficientemente para situaciones de vida verdadera.
In addition to providing classes, Habla Ya also helped arrange the various eco-adventures Tori and I did. Supposedly, this resulted in some savings; at the very least, it was convenient.
One other side benefit I did not anticipate with taking the classes was meeting and seeing the same (or new) friendly faces every day, including staff and students. When traveling in a foreign country where you'd otherwise know nobody, that provides additional comfort and memories.
