Hi Ross2018,
When it comes to studying for the GMAT, there are a variety of different study materials to choose from (and you'll likely end up using a 'mix' of materials). So to answer your initial concern - No, the free Veritas materials will probably not be enough (on their own) for you to study with and hit your Goal Score.
You're clearly interested in continuing to study so that you can score higher. Before I can offer you any additional advice that you’re looking for though, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied?
2) What study materials have you used so far?
3) How have you scored on EACH of your CATs (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your goal score?
5) When are you planning to take the GMAT?
6) When are you planning to apply to Business School?
7) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
