Verb conjugation of "sucer" in French

In order to improve the language skills we changed some features on Vocabulix. From now on users can not only drill isolated lesson but adhere to a specific lesson plan. That means that they can set goals and seek help from other users.
Therefore we use only the Vocabulix dictionary in our class. It has good features and a large vocabulary base. I will have to send you a few sentences for rewriting if that is OK with you, because the whole is mixed up.
How long have you been practicing Spanish using this site and in which lesson are you now? I am now at vocabulary lesson number 3. It is still hard for me, but I'm quite new here and need to get better.
