I see that you have changed the answer for 17 c) to 779.

But what I remember of the series given is that

2 ------------------- 20
3 ------------------- 28
4 ------------------- 33
5 -------------------- 41
6 -------------------- 46

Can anyone confirm this for me ?
How can a P6 student confuse this series with

1---------------------- 12
2 --------------------- 20
3---------------------- 25
4---------------------- 33
5 --------------------- 38
6 --------------------- 46

For Compo,I chose question 3.

That's my compo.

The class was yawning away as the teacher went on and on with his monotonous tone.\"Ring!\" The school bell rang to signal the end of school.I sat up right,just like all my other bleary-eyed classmates,waiting for the teacher's signal to dismiss us.When he did,we sprang out from our seats and rushed out of school.

\"Jane!\"my friends,Amelia and Eunice called out for me.\"Hello!\"I shouted back while waving my hands at them. Together,we walked to the bus stop.
Time seemed to pass so slowly (Improvement: The wait seemed like eternity.... ) while waiting for the bus to arrive.Suddenly,an elderly woman walked unsteadily (staggering) towards our direction. Concerned,I rushed over to give her a hand.\"Are you alright?\"I asked.\"I have just been robbed! The robber pushed me and I fell,my legs hurts now...\"she replied.

I was stunned.My instincts nudged me that we should report this robbery case to the police!Just then,my friends walked towards us and asked what (had) happened.I told them about the elderly woman's mishap and we advised the elderly woman,\"We think that you should report the incident to the police.We will accompany you along.\"She nodded weakly, (apparently,she was[not really needed]) still shaken from the sudden turn of events.On our way to the police station, we supported her and also offered consolation to her.

When we reach(ed, [arrived]) there, the elderly woman was asked to give a statement. After that,the police officer and the elderly woman thanked us for our quick-thinking of advising the elderly woman (her) to report the case to the police.I smiled sheepishly.The police officer then informed the elderly woman's son to fetch her.

Knowing that she would be well-taken cared of, we left and headed back to the bus stop. I could not help but beamed with pride on my way home as I had done a good deed and that's a fact.

Wondering how much I would get? :?:

I would give it a 30-31. How much do you usually score in school?

Urm on average I would say a 30?

For Compo,I chose question 3.

That's my compo.
