1. It is estimated that about 40 per cent of the world's population use social media, and many of these billions of social media users look up to influencers to help them decide what to buy and what trends to follow. An influencer is a person who can influence the decisions of his or her followers because of his or her knowledge or special knowledge in a particular area, e.g. fashion, travel, or technology. Influencers are now seen by many companies as a direct way to customers' hearts. Brands are now asking powerful influencers to market their products. With some influencers charging up to $25,000 for one social media post, it is no surprise that more and more people are keen to become influencers, too. If you are one of them, then here are five tips on how to do it.

2. Choose your niche: What is the area that you know most about? What do you feel most excited talking about? Find the specific area that you are most interested in and develop it.

3. Choose your medium and write an interesting bio: Most influencers these days are bloggers and micro-bloggers. Decide which medium – such as your own online blog, Instagram or Snapchat – is the best way to connect with your followers and chat about your niche area. When you have done that, write an attention-grabbing bio that describes you and your speciality area in an interesting and unique way. Make sure that people who read your bio will want to follow you.

4. Post regularly and consistently: Many influencers post daily on their social media accounts. The more you post, the more likely people will follow you. Also, make sure that your posts are consistent and possibly follow a theme.

5. Tell an interesting story: Whether it is a photo or a comment that you are posting, use it to tell a story that will catch the attention of your followers and help them connectwith you.

6. Make sure people can easily find your content: Publicize your posts on a variety of social media by hashtags and catchy titles to make sure that they can be easily found. There is no point writing the most exciting blogposts or posting the most attractive photographs if no one is going to see them.

7. Most importantly, if you want to become a social media influencer, you need to have patience. Keep posting and your following will gradually increase. Good luck!

Read the following passage about the Youth unemployment and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions.

    [I] Youth unemployment has become a pressing issue in Vietnam in recent years, particularly among graduates. [II] As the economy continues to grow, the influx of young people entering the workforce has outpaced the availability of suitable jobs. [III] Various factors contribute to this challenge, leading to significant consequences for both the economy and society. [IV]

    Many factors push young people into unemployment. For instance, a mismatch between education and job market demands often leaves graduates without the skills that employers require. Furthermore, the competitive job market means that even qualified candidates struggle to secure positions. In contrast, there are opportunities that attract youth to urban centers, where industries are more concentrated, providing potential access to better employment prospects and a higher standard of living.

    The impacts of youth unemployment are far-reaching. First, high unemployment rates can lead to increased poverty levels among young adults, which in turn affects their overall well-being and mental health. Additionally, the lack of stable jobs can result in social unrest, as frustrated youth may engage in protests or other forms of activism. Finally, this phenomenon can lead to a brain drain, where skilled young people migrate abroad in search of better opportunities, further depleting the local talent pool.

    Addressing youth unemployment is a complex challenge that requires a comprehensive understanding of its causes and effects. By implementing effective educational programs, fostering entrepreneurship, and encouraging job creation in various sectors, Vietnam can better support its youth, providing them with opportunities for fulfilling careers and contributing to the economy without sacrificing social stability.
