DAY 1: 25 May



Today is a nice day, the math homework is not too much, not too little, just nice for the 1hour slot. However the power point slide on the wiki is quite troublesome, having to click once for every slide and it plays very slow. I also think that this topic should be placed together with the topic for day2 as I do not really think that it is necessary to split it up into 2 separate days as I think that the 1hour slot on day 2 should be used for another subject. Lastly, I like this kind of lesson as it is not long winded and there is a summarised version of the whole thing which made it easy for us to learn.

DAY 2: 26 May

I slept too much today so there was a rush to do the home learning. For today's topic, I found it difficult to understand as I always had problems with quadratics. I think that complicated topics like this should be split into 2days and teach since not many people understood fully. Yesterday's topic was like a revision on pythagoras theorem so I felt that we should have touched a little bit on the equation of circles with the time left after covering that topic. Lastly, I will appreciate if there is a manual for the GC as I forgot how to use it
