Kara: Bienvenida a Rocket Spanish!
I can tell you what my study plan is, and others will do the same, but in the end you need to figure out a plan that works for you.
My plan has changed quite a lot from when I started Rocket Spanish a little over a year ago. This is what I am doing right now:
First thing every morning I study what I call a "current" lesson. By that I mean one that I have not previously studied. In the case of an audio lesson, I listen to the audio once over, then usually once or twice more while reading the accompanying transcript carefully. When I come across a new word I will stop to learn what it means and if it is related to another word I already know. After this I go through the conversation transcript and additional vocabulary sections, listening to each line, writing it down, and repeating the line. Then I move on to the testing lab, again writing down each phrase as it is presented, and repeating it in Spanish, for each of the Hear it-Say it, Write it, and Know it sections. It takes me a long time to go through a lesson this way, but I find that I have learned a lot when I am finished.
You will find that there is usually a language and culture lesson that corresponds with the audio lesson. So when I have finished the interactive audio lesson I move to the corresponding language and culture lesson and repeat the process I described above.
I think that listening, speaking, reading and writing are all important learning activities, so usually as I am eating breakfast I read a page in a basic Spanish reading book I bought, which comes with some questions to which I write out the answers to.
It seems to me that verbs are critically important to learning Spanish, so I have developed a habit of looking for new verbs as I go through the lessons, and adding them to a study set in Quizlet that I study every day. I often do this while I am driving or doing something else (the program speaks the English verbs to me and I answer with the Spanish verbs, in case you are wondering!) I also typically select a random verb and conjugate it with the tenses I have learned to date (present, preterite, and imperfect.)
Finally, awhile back I decided to review the lessons from the first course. So late in the day I work on one of those, usually just going through the testing lab and writing out the answers to the Hear it-Say it and Know it sections.
You may notice that I do a lot of writing. In the My Toolbox section there is an article on the Scriptorium Technique, which I adopted a couple of months ago. I think that it has accelerated my learning to a great degree.
All in all, I spend 2 or more hours a day studying Spanish, spread throughout the day. As I said, my plan won't work perfectly for you, but might give you some ideas for your own plan.
