Yes, you may re-apply after the conference, as it is possible that there will be additional funds available at that time. Please keep in mind, though, that re-applying will not guarantee funding.
No, you will not receive funds for any expenses related to food and drinks (alcoholic or not), or for any amenities (i.e., internet connection fee, mini-bar in your hotel room). Funding is limited to conference registration fees, hotel room cost, and travel expenses (i.e., plane, train, or bus ticket).
All students who attend professional conferences are eligible to apply for funds. However, because funds are limited, precedence will be given to those students who present at the conferences.
Unfortunately, because funds are limited, applying for funds does not guarantee that your conference-related expenses will be covered. In addition, even if you are awarded funds, you might be compensated for only a portion of your expenses.
Your supervisor will complete a brief mid-semester evaluation. Then, toward the end of each semester your supervisor will fill out an evaluation form that you and he/she will discuss. These evaluations are intended to help you learn about your strengths and weaknesses as a developing professional.
