Scholarship Application Tips in 2013 for college students

·Before you apply

1. Work hard to get good grades. Don’t sweat about one bad grade, but always strive(力求)to do your best.

2. Get involved, and stay involved, in extracurricular(课外的)activities. Sports, clubs, drama, bands and orchestras－these often count toward a student’s overall scholarship application evaluation. The same goes for paid (or unpaid) work experience.

3. Begin your scholarship research early－by your sophomore(大学二年级)or junior year of high school, if possible. Make special note of application deadlines, as they can vary from late summer to late spring.

4. Apply for as many scholarships as you are eligible(符合条件的)for－several smaller scholarships can add up to a lot of money.

·During the application process

1. Read the supplementary materials that come with scholarship application forms to better understand the program’s focus (community service, subject interest). Try to answer the questions with the focus area in mind.

2. Answer questions as they are asked. Don’t got off topic.

3. If there is a financial component to the application, make sure you get accurate and complete information from all appropriate sources to ensure your eligibility.

4. Take your time. Write down everything you can think of for each question, then set the application aside for a day so you can look everything over again before you send it off.

5. Don’t wait until the last minute to complete your application, especially if you are applying online. Computer systems can get clogged(阻塞的)with the large volume of applicants hoping to submit their qualifications during the last few days and hours before a deadline.

6. If a third party has to complete part of your application, such as providing a letter of recommendation, make sure you ask them early on and remind them as often as necessary to ensure they provide you with the necessary materials.

7. Last but not least, review your application with your parents to make sure you haven’t left out any important details.

Good luck to the students applying for the 2013 scholarship programs!
