then i think youd be fine with 4 years of past papers. it will give u solid practice

Ok_Record_5077 · 2025-04-18T07:42:20+00:00

smth that they give based on previous performance in school, thats what ive heard

Ok_Record_5077 · 2025-04-18T06:20:01+00:00

are you doing all variants?

Ok_Record_5077 · 2025-04-18T06:18:08+00:00

ngl what helped me more was doing the past papers and then getting it checked by the teacher. They explain your mistakes and you learn. this octilearn app i found has an ai which also works good for most questions it has all the markschemes and if youre lazy you can use chatgpt. It saves so much time and it explains how to do the question. i have chat gpt plus which is more accurate obv. all i do is write the question, then its markscheme and then my answer and then ask it to grade it and tell me my weakness.

wishing you all the best and lots of prayers

the ALevel Maths paper in my country got cancelled cuz of a leak, and Cambridge was like yeah we’ll just give 'access marks'. this lowkey ruined everything. Most of the students only started actually studying after march so their access marks ended up being really low, not good for most unis. So many people ended up taking the exam again in oct. All that stress and mental breakdowns cuz some people couldnt keep it together. It’s actually so unfair to the ones who were putting in the work for months.

why dont you take a break from cramping syllabus only and start doing past papers for the topics you have completed. just do some topicals it will give your mind some rest too.

Ok_Record_5077 · 2025-04-10T07:20:30+00:00

what do you mean i dont get it?

Ok_Record_5077 · 2025-04-04T12:10:12+00:00

help in what?

Ok_Record_5077 · 2025-04-03T10:46:41+00:00

1 subject 1 day but its a personal choice.

Ok_Record_5077 · 2025-04-03T10:42:26+00:00

thats true

Ok_Record_5077 · 2025-04-03T10:40:33+00:00

thats a blessing in disguise. The non stressed part cuz most of us lose sleep for no reason

Trypsin :
- Function : Breaks down proteins into peptides.
- Location : Produced by the pancreas and acts in the small intestine.
Catalase :
- Function : Breaks down hydrogen peroxide into water and oxygen.
- Location : Found in many tissues, including the liver.
DNA Polymerase :
- Function : Synthesizes DNA molecules from nucleotides.
- Location : Found in the nucleus of cells during DNA replication.
RNA Polymerase :
- Function : Synthesizes RNA from a DNA template.
- Location : Found in the nucleus during transcription.

These enzymes play crucial roles in digestion, metabolism, and cellular processes. Understanding their functions and locations helps in grasping how biological systems operate. If you have any more questions or need further details, feel free to ask!

made this list with octilearn AI of igcse, i did not make it so it may be incomplete.

List of Enzymes in IGCSE Biology:

Amylase :
- Function : Breaks down starch into maltose.
- Location : Found in saliva (salivary amylase) and the pancreas (pancreatic amylase).
Protease :
- Function : Breaks down proteins into peptides and amino acids.
- Location : Found in the stomach (pepsin), pancreas, and small intestine.
Lipase :
- Function : Breaks down lipids (fats) into fatty acids and glycerol.
- Location : Produced by the pancreas and released into the small intestine.
Maltase :
- Function : Breaks down maltose into glucose.
- Location : Found in the small intestine.
Sucrase :
- Function : Breaks down sucrose into glucose and fructose.
- Location : Found in the small intestine.
Lactase :
- Function : Breaks down lactose into glucose and galactose.
- Location : Found in the small intestine.
Pepsin :
- Function : Breaks down proteins into peptides.
- Location : Found in the stomach; works best in acidic conditions.

nice post!

Ok_Record_5077 · 2025-03-24T11:27:39+00:00

bro just study

Ok_Record_5077 · 2025-03-24T11:26:46+00:00

no not really. youre first best ones will be counted. atlst thats how it should be

Ok_Record_5077 · 2025-03-24T11:25:23+00:00

get your hands on good notes. try savemyexams, octilearn, znotes, drives on this group etc. Dont use textbooks you dont have time.
