Dear all, PF has a great resource in the form of the Mathematics & Science Tutorials Sub-Forum, over the years many people have posted links to some great online resources and references, some members have also contributed their own material to the forums. There are now over two hundred threads containing tutorials, summaries, lecture notes and video lectures. The purpose of this thread is two-fold; firstly, to raise awareness of the Tutorials Sub-Forum and secondly, as a place to gather feedback and suggestions for the Tutorials Sub-Forum. To get the ball rolling I suggest the following points of discussion: 1. Did you even know that we had a Tutorial section? 2. Do you ever use it, if so how often? 3. Have you found any of the tutorials useful? 4. Have you considered adding a tutorial of your own? 5. What do you think of the quality of the tutorials in the forum? Any other comments or suggestions from all members are more than welcome.
