I strongly advise against doing that. Boring as it might be, the exam will be about what the teacher is saying in class, and not about the content of some course on the internet.
Sorry ChairmanPoo , thank you for your advice , but according to the educating situation nowadays in my uni ,the free course videos on the Internet platforms such as bilibili might be a better choice . You might not able to deny the academic research skills of the professors , but it is worth to doubt about their teaching skills . Senior officials do not judge the professors on the level of educating students especially the undergraduates , the dissertation they posted on SCI plays an important role . Such situation makes it common for the professors to cope with educating causually (such as my histology teacher ,who just repeated the text on the textbook ). The first term I entered my uni I heard a proverbial "大学大学,大不了自学"(university , university ,at worst , self-study ), and it's an ironic phenomenon that the course online might be beneficial to your study a lot .
Thinking about the countryside life , I often connected it with my sweetie childhood memory since I grew up in countryside .Each time I felt stressed out , I would always recall those happy times Things were totally different in my grandparents ' and my maternal grandparents ' countryside .
grandparents : A little bit Poor village (compared with other areas in Jiangsu Province but much richer than most areas in China ) has a unique family name "Zhi(支)" for all the villagers which shared a similar culture to the Shandong Province , where I started my uni life , somewhat overcrowded and polluted . There is no place of interest but simple and generous villagers .
maternal grandparents ':A village near the sea where I spent more time in my life there , according to the tales told by my grandfather, , this town was totally created by the migrants from the south of Jiangsu Province in a gruelling life under the initiation of the government , comparing with the village above ,here there are lots of places of interest such as the Dutch Flower Sea (4 star scenic area, maybe worth your visit I should say), a vast western style tulip garden with some western buildings around and the Dafeng elk natural protecting area . It is also famous for the red-crowned cranes there (at most 600 in winter for overwinter,good for your birdwatching ).
It might be out of the topic of this thread "Things that made you mildly upset today", but posting about these make me feel free away from the friction and upset accumulated in my daily Life ,hoping that you bay watchers could understand me .
