Advantages and Challenges
Dual study programs have plenty of advantages, but they aren't for everyone.
If you have a desire to work in a specific area of industry (such as car design, or network management), having the chance to work in relevant settings, and the opportunity to build contacts is absolutely invaluable.
Some people will thrive on the vocational nature of these courses. If individuals aren't academically minded, and struggle with research, they may do very well in work-based environments, and discover talents that wouldn't normally emerge in conventional universities.
On the other hand, admission is competitive, and international students will need to work on their German both before and during their studies. They also need to be sure about their career direction, which not all young people are. And even though students can earn money, the income received isn't always enough to live on. For some people saving for standard degrees, and working mini-jobs between semesters can be more convenient.
Dual study courses also lead to focused qualifications that aren't always applicable across the whole of society or abroad. General degrees may open more doors, or lead to further study. But there's no doubt that vocational dual study courses can deliver huge benefits. Just think carefully before applying.
If you are unsure about whether to opt for dual study or conventional degrees, feel free to ask academics or industry professionals. And think about asking wider communities on sites like Quora. The feedback from members can often be very helpful.
