Notification and revision

Sorry..
so long din update le....
By dis week i will update my "balik kampung"...

So let's do some revision since the end year exam is coming...
er... how bou physics...?
ok... those who take tuition at mca have 2 ear squat 10 times for each question they answer wrong...
coz all question took from the paper Mr.Liew gave us...

Still more to come...
4 those who are sitting 4 their pmr....
relax ur mind....
I neo u can do it...
especially cindy...
U are the best in my heart....
