answer:I’m sure different students will seek different apps depending on what they’re majoring in to. Google translate is a popular one for general uses in language-oriented class, WPS office allows you to work/fix your work on phone, any photo-editor apps will help if you’re in photography or visual-design class, and I’m sure there are many more depending on what feature you’re looking for. I must also mention that there are ‘games’ in nds that are made to help people that have taken interests in certain field (and you can utilize this using a nds emulator for your mobile phone), for example if you’re a student majoring in certain language then “My Spanish/Japanese/Mandarin Coach” will definitely help as well as entertain you in learning a specific language. If you’re in to culinary class then “Personal Trainer: Cooking” will be a great addition for your cooking practice.
