Thank you all for working through the tutorial questions. I noticed that there were some problems on some indices questions. I will be moderating your marks accordingly. If you have encountered other problems with generation of the questions (possible if the network drops the connection). If that happens, Grade and Save and Quit, and come back again. A fresh paper will be generated.

I have added two further sets called Miscellaneous Revision Paper 1 (5 questions), and 2 (10 questions). If you can complete these two papers satisfactorily, you can be confident that you have the necessary skills of the basics, and can make further progress.

Please do try your best and let me know if you have any queries.
