It takes a long time for the light to reach us so by the time it reaches us, we will see the star as how it was when the light started to travel towards us..
if that made sense


thts not making sense to me.... how its related to the past?

Okay so you have galaxy A and we are galaxy B. Galaxy A is 8 light years away from us. Therefore, it takes 8 years for the light to reach us, therefore we see it as 8 years in the past because it took that long to reach us

What did you get for the last six marker and the Mercury question btw don't worry the grade boundaries probably low

i missed one of that question didnt had time at all... basically i missed 2, 6 marks qs so yeah definitely failed it.... :smile:

I have a feeling that the grade boundaries are going to be low for that exam tbh (i took it too, wasn't hard but was harder than the 2014 paper)


Nope the 2014 paper was really difficult, quite a few of my friends took that and struggled this year was easier than that paper.

Also think about it this way you have physics to redeem yourself c:

i got an A* in physics and A's in chemistry and biology in 2014 pastpapers but find 2015 difficult so i do think that the grade boundaries gonna be low

they lowered the grade boundaries last year, I don't think they'll do it again tbh

i know but i still got very higher marks 50 out of 60 in physics others was also high... but it depends on the student's performance they lowered the grade boundaries because of the candidates performance and they might do this again low the UMS marks because i dont think anyone find it easy exam this year too!!!

Yep the Mars question wasn't bad because you just had to explain the composition of old earth, explain how it changed then compare it with Mars. I came remember the other 6 markers on the chemistry paper.
And on the whole biology was easy because I revised everything that was there.

yeah i know that qs wasnt hard thats why i spend about 10 to 15 minutes explaining the whole theory and also asked for an extra paper; i ran out of the space and i have revised that topic specifically and i didnt had time to do other qs i really rushed it and just guess them :frown:

I write really quickly anyway so I always finish earlier in exams than other people do. Like if I don't write this quickly I wouldn't be able to write down everything I want to say XD
I usually gain time from other questions to use for 6 markers though aswell
