During the study, I met many many problems and the support such as TA and QuantNet website was not efficient and enough at all. I have to emphasize that the support from the TA and the QuantNet website is very very limited and is quite frustrating sometimes. Because you meet a bug, then you ask a question, then you have to wait for response which at most time are not useful at all. After you got a response, you try as what the TA suggested, then you meet another bug, then you ask again, then there will never be a response... After several times you will realize it's just a waste of time and it's better to learn by yourself.
Regarding the materials provided by this course, I think they are not sufficient. The videos only cover a bit useful knowledge, the PDF material was written without care. If you like, you could find that the materials include very few comma. The write seems like he/she doesnot care if the students could understand the materials at all.
Instead of videos and materials provided by this course, I basically learned the knowledge for every exercise by myself, which were quite difficult. Because you never know what the next bug will be.
Therefore, all in all, it was not a pleasant journey for me to study this course. I dont think it is worth the tuition at all.
