Dear senior expert, if anyone has audiovisual materials from Teacher Dong Meiying on the Mechanical and Electrical Engineering subject for the 2015 Level 1 Constructor exam, please upload them to me or provide a link. Thank you very much. 852185026@qq.com]852185026@qq.com
This video material by Dong Meiying is really good; I searched online to see if it could be helpful http://club.topsage.com/forum.php?mod=viewthread&tid=3953674 http://www.1k9g.com/thread-20349-1-1.html, but it seems unlikely that they are audiovisual materials?
Dong’s classes are not all available here; she gave lectures at Xueersun last year, but since she signed a contract for online courses, recording is not allowed.
I’ll help with this issue. The link sent by Brother Pingdan Shi is invalid; it’s up to the poster to determine whether the information provided is complete. I have the complete version, and I’ll post it on the forum tonight. Also, I’ve received the message you sent me, Pingdan Shi – it’s fine.
