It was hard but easy if that makes sense. The arithmetic series question got me until i figured it out and im unsure about the consumer arithmetic question. The last question was easier than i thought

I would like to think 115/120 atleast

Click to expand...

mine skool edited the cathic paper aswell. i did the garden bed semi circle question!! didnt get the maximun area though. dont no how much was cathlic and how much was their own...

ours was ok, normally we have really hard tests that we all just pass or mosty fail. was happy, but then again. when i think i do ok i normally do bad and visa versa!!!

i had NO idea wtf that money one was

and that stupid athlteic practise question i know its easy, but i haven't touched those kind of questions in yonks, so i was doing it one by one, was the total metres like 5544 or something?

and rofl my theta for that blade question was 1 :/ so my area worked out to be 4 hahahah ah well... what to do!

i couldnt get 10 C i had nfi., but i think i got the others right like 25/tan@ and sin@ /50 or some shit

that velocity q was easy as hell!!

yeah so 20-25 marks lost >.<
ah well thats my fault in the long run, i was practising of way easier CSSA papers compared to this one, when i could have practised off hsc papers.

God I'm dumb! plus i still got extension to go tomorrow, where yet again i suppose i'll crap on (kinda like i'm doing now... i'll shut up now!) Good luck to any1 else doing extension!

There was a question in the exam (i think its q9 or 10) where there was a table of values given and they asked u to show x= something.t. its was worth 3 marks tho i found it incredibly easy, maybe i did it wrong. all i did was substitute the values from the table into the equation to proove it. or is that the wrong way of doin it?

Was it just me or was that exam a lot harder than past catholic trials?

I hate all the general proof crap. Give me a couple of numbers and I'm sweet, but tell me to prove why the natural rate of exponential growth formula is how it is and I've got nothing but a sore head.

Super annuation Question

Did anyone else get around $96000 for the super-annuation question? (Q 9)
Everyone said they got like $36000 but i added the compound interest...

i got both answers from two methods and didnt know which one to use so i picked the 96000 answer cause i assumed that the money he already put in would earn interest but thats the only question that troubled me. With 36000 the money he puts in doesnt gain interest, its just how much money he put into the account
