Give the course you choose your undivided attention re dont get distracted by 6too many parties
Apply yourself 100% to the work
Ensure that you fully answer questions with good grammer and spelling
Work hard and research your course and the materials
Pay attention in lectures
Do not get on the bad side of the lecturer
Always attend scheduled lectures
Always be on time for said lectures
Pay close attention during lectures and take notes....
Choose subjects that appeal to you as you may find boring subjects you will lose interest quicker.
ps dont be afraid to ask your lecturer for help/advice/guidance type stuff if you are struggling, if your lecturer is aware of the problems they can assist you rather than thinking you are under performing due to social reasons and not because you havent fully grasped a concept.
I particularly struggled with the economics section which was part of the degree but my lecturer was helpful when i stated i was having difficulty and this is probably true in most cases. If they dont know whats going on they cant help you....
