Many students need to work to afford studying. Therefore, many universities assign funds to research groups to offer students small jobs to support them in two ways. The student can learn how it is to work in a research group and get to know the day-to-day life of a scientist. He or she can learn a lot from the contact with other scientist. In addition he or she can earn a small amount of money to support his or her academic studies. These small jobs are usually very motivating for students since they can see directly what they are learning for and can help them to get a clearer picture for their future.
