same for me srsly after viewing the solutions someone posted here i cant believe i even made those mistakes in the actual hsc

RIGHTT

 

[person3024]

that not that bad, math is hard, I'm gonna fumble biz and bio, hopefully get like raw above 70 in legal, but prob not ,
I do have hope fo scaling tho, cause according to

HSC Raw Marks Database

for bio in 2022 a 53 are mark aligned to a 71

and for biz in 2022 a 68alinged to a 80
and in 2021 a 66 alinged to a 80, so both years that's a band 5

bro i rllyyy hope i can get a band 5 for bio but i dont know at this point im still learning content, i pulled through with a good mark in trials w/o study and no sleep for 2 days but i dont wanna risk that again but ahhh i dont wanna study

 

[e8zks]

do uk the mark ranges for each band?

no sorry

I got a 62 for trials, I ain't pulling any more that that in hsc, like what do u think we should study, like is there any consistencies over the years
or stuff that is tested more than others

i got like a 70 but the highest was 72 and it was cssa
i feel like hormones and epidemiology because those are usually harder and people struggle with them, i also gotta go over my skills with graphing and validity stuff omg

I suck at all of the cell replication, transcription, translation stuff, miosis, and mitosis stuff, and I don't get the adenin, guanine, thyninc, stuff,

i just did a whole revision on all of that lmao because its so common, and wym by that

how did u get it in your head, I just don't understand it,

 

[person3024]

how did u get it in your head, I just don't understand it,

is it for dna replication, protein synthesis or both, like which specific bits
i just kept reading over it tbh it was one of the easier parts of mod 5 for me because we had a whole assessment just on polypeptide synthesis and i did a lot for that (still struggling with mitosis and meiosis though)

I find videos the best way to remember, or making diagrams yourself and then annotating what happens at each process. You can also recite the process like your teaching it to someone else

everything I said I struggle with

 

[hante]

extension 1 maths in like an hour i am so cooked

 

[lyingsalsa]

im backkkkkkkkkkkkkkkkkkkkkk

 

[e8zks]

im backkkkkkkkkkkkkkkkkkkkkk

and blackkkkkkkk

 

[idk123233]

no it wontttt
and I haven't studiedenough for bio, legal and biz, and biz is tommoorow and I haven't studied anything, and I just want to die, like why is HSC 50%, like50% is so dumb, what about all the kids who don't do well in exams
kill me now

same me too bro, havent touched legal or bio

 

[katiekms]

guys why is nothing sticking in my head. I'm at school so I cant speak to memorise ahhhhhh

 

[lyingsalsa]

and blackkkkkkkk

back in black. i hit the sack. its been too long, im glad to be back

 

[sharknado]

fr I'm so tired and demotivated I literally cannot study anymore even though I have an exam in a few hours

You need to remember all of them
DNA replication - I’ll make a step by step list on how it goes:
1. Helicase enzyme unzips the double stranded DNA molecule on one strand. The separated strands are the template strand, which will form the basis of what the new strand will be. The gap between the strands is called replication fork (fork in the road).
2. Primase enzyme adds primers to the broken up nucleotides, where free-floating nucleotides can join to the strands. (Think of priming before painting).
3. DNA polymerase adds these nucleotides to the strands, starting from 5’-3’ (this is the leading strand, as it moves towards the direction of DNA with 3 carbon molecules on the phosphate group. Polymerase adds this pretty straightforwardly to the leading strand, and checks for any errors.
4. The other direction from 3’-5’ is known as the lagging strand. DNA polymerase adds these differently by segmenting the lagging strand into ‘Okazaki Fragments.’ These have primers on them and are done a few at a time from the phosphate end so that both the parent and daughter strands can have nucleotides attached.
5. Exonuclease enzyme removes the primers (think ex like the X as a delete button).
6. Ligase enzyme (the gluing enzyme) joins the strands together securely, which reconnects the daughter strands to form a functional DNA molecule. Same as for the parent strand.
———
we call this process semi-conservative cause it uses the original DNA molecule as a template to create a new one.

Protein synthesis is pretty much polypeptide synthesis (polypeptide = many peptides or amino acids in a long chain. Once it is complete, it folds into the protein.)
that’s usually a big part when they have a question about like a genetic disorder caused by a mutation to the nucleotides affecting proteins. You should be familiar with how that works since u did an exam.

Meiosis and mitosis i gotta revise a bit more, but way I remember it.
MITOSIS = only 1 phase, used for somatic cell replication and repair. Basically it has all the traditional steps (interphase, prophase, anaphase, metaphase, telophase, cytokinesis). The cells created from this are called diploid cells that are created, because two are made.

MEIOSIS = OCCURS BEFORE FERTILISATION; THERE ARW TWO PHASES.
-during prophase I, the homologous chromosomes randomly cross over to create new alleles. then, during meiosis II the chromosomes split into four haploid (haploid = half a chromosome) cells (individual sister chromatids) which form your gametes (sex cells—> sperm/ova depending on sex)

hope this helps

SAME bro. I woke up late and now im rushing to school. Couldn’t remember much of the artworks for the life of me. Nor quotes from the artists which my art teacher always tells us to do. FML.
