Meta-cognition is thinking about thinking, and higher levels tend to be associated with intelligence and - in the parlance of the times - high income and job satisfaction. So, to keep things simple: if you think that you might struggle with learning concepts in statistics or research methods, then get in touch with a tutor early. It's important to establish some type of relationship so you can evaluate their style, methods, and how likely it is that you'll be successful within their approach. If you wait too long, or right before an assignment is upon you, you may be stuck with a limited number of tutors that you are forced to work with.
Prevention through establishing early contact will help you iron out details, assess a match in learning and tutoring styles, and prepare for mastering any difficult concept.
Don't wait - contact tutors before it's too late!
