Since they haven't given you the test results regard this as a fact finding meeting not a decision making one (on your part). At the end explain they have had x time to consider the results and you will respond by y time. It is easy to get steamrolled into an unwise decision. Plus 1 standard deviation isn't that much but he could be plus 3 for all they have told you and it makes a big difference. If you can pay $7000 without extreme hardship try and leave that out of the decision making process but be aware you paying them that $7000 might be a big part of their dwcision making process.
