For students taking CIE 5070 Chemistry, I would be uploading solutions to the MCQ papers from pervious years.

http://metatutorchemistry.blogspot.sg/p/this-page-contains-mcq-solutions-to.html

Besides providing the correct answers, the solutions would explain how these answers are obtained.

I believe these resources would be helpful not only to students taking CIE 5070, but to all students taking high school chemistry.

Videos Hosted on Dailymotion

For students without access to YouTube, I am now uploading videos to Dailymotion. 

It would take a few days as the website limits the number of videos uploaded per day. c

This is the link to my Dailymotion channel.
