the BB or the official tests?

<p>hey guys, am an international giving SAT1 this december!! well currently am in a dilemma whether i should go on with the BB papers or should i rather start with some official SAT papers? I mean, i've already completed pretty much the whole BB but 2-3 tests in between and now i've got some official administered papers (2009 ones)! should i start with the NEW administered papers that i've acquired or FINISH the BB first? please suggest asap!!! :&lt;/p>
