Final answer:
SmartBook Recharge mode is false. It becomes available after completing an assignment and is meant for reviewing material, not accessible anytime during an assignment.
Step-by-step explanation:
The statement "SmartBook Recharge mode can be accessed at any time during a SmartBook assignment attempt" is false. SmartBook, part of the McGraw Hill Connect platform, is designed with adaptability in mind to help students study more effectively. However, Recharge mode is a feature that is specifically designed to help students retain the knowledge they have already learned. It becomes available after they have completed a SmartBook assignment and some time has passed, to encourage reviewing previously covered material.
