Can meditation help students in exams? Came across this interesting research paper: Harvard Unveils MRI Study Proving Meditation Literally Rebuilds The Brain’s Gray Matter In 8 Weeks

If above is the case, is there any research showing that meditation makes better students or make people fair well at exams? Does it boost your IQ / EQ?
Here are references to some studies on this.  I don't know how rigorous they are!

An abstract of a study:

Two articles in the Huffington Post that reference studies.  I imagine trying to google the universities and professors involved might get you some abstracts or summaries of results:
