So, you're an ex-seftoner! Hey, does the English faculty let any students from Standard move up to Advanced? I want to move up. Ms R said yes last year and first term but then she keeps changing her mind.

Yeah. Gotta admit that year 12 sounds terrifying

Dont worry about the SC. It is in November and you guys are worrying now? The SC isn't important, and I'm sure you will do better than you expect. I got all Band 6's but one Band 5 in the SC and look at me now.. I am aiming for 59 UAI :D THe SC doesn't affect you in any way. Just listen in class...

I dont want to go to year 12. I wanna be a year 10 forever. Feelings? I feel nervous and sad because my life is going to be over soon. I will definitely cry on my graduation

Yes. Your average uai at Ruse was quite high and you are an above average student. You also have high scaling subjects there EDIT: you'll get your uai...but you need to maintain those ranks and marks

Read over 7 times, then write without looking

maybe its just your school syllabus that's hard. what school do you go to? okay. in that case, do 2 unit. Dont do general maths unless you have tried 2 unit

Try 3 unit since you do 5.3
