Hi Pablo,
Welcome to Veritas Prep! I'd be happy to answer a few of your questions.
2. You are so bold to post your score! I attended a class last night and one of our students stated that he'd give up who he's voting for before he would tell what he scored on his GMAT. Also, 570 is not a lame score, the average score is about a 530. To answer your question, on average, our Veritas Prep students notice about a 60 point increase.
3. Typically, we suggest about 3-4 weeks of study time after our Immersion Course, but since you won't have work awhile you are here, I think you will be in good shape.
Please feel free to contact us at headquarters if you have any further questions or concerns! 800.925.7737
Happy studying!
