I am a geological engineering major in Chang 'an University 10. After the start of school, each class has its own QQ group, which is required by the counselor. So, don't worry now. If you have to add one now, you can build one yourself, and then send your own QQ group to Chang 'an Daluo Yanfeng netizen group ① 19698020 and Chang 'an Daluo Yanfeng newborn group ④4632479. Just say that if you build a QQ group of 20 12 geological engineering, there will naturally be students of 20 12 geological engineering.
