Helloo the crash-course lecture will be hosted tomorrow online (24/8) at 830pm! If you have specific qns, drop a dm or you can raise them during the session ❔❗️
O must be in the middle for H2O2 because it can form more bonds. It's not possible to have H in the middle since it forms only one bond.
[Os] chem bonding
This is the structure of H2O2:
H-O-O-H
Method 1:
Non-bonding electrons = Total electrons - Bonding electrons
Each O has 8 electrons (2.6), while each H has 1 electron. There is a total of 18 electrons.
With 3 single covalent bonds, 6 electrons are involved in bonding.
Hence, there are 12 non-bonding electrons.
Method 2:
Drawing out the structure H-O-O-H, each O has 4 non-bonding electrons in the Valence shell.
We also need to include the 2 electrons in the inner shell of each O.
Hence, there is a total of 12 non-bonding electrons.

Common Biology Command Terms (Expanded List):
1. Analyse: Break a concept, process, or data into its key parts and explain how those parts relate to one another.
2. Compare: Identify and explain the similarities between two or more items, referring to each throughout the response.
3. Contrast: Identify and explain the differences between two or more items, referring to each throughout the response.
4. Deduce: Reach a logical conclusion from the information given from the question/diagrams.
5. Discuss: Consider different perspectives & hypotheses, explain them, and use evidence to support your final judgement.
6. Evaluate: Judge the strengths and limitations of something before reaching a conclusion which must be supported by sound evidence and logical explanations.
7. Determine: Find the one correct answer.
8. Explain: Give reasons and describe why or how something happens.
9. Predict: Say what you think will happen based on the information given.
10. Analyse: Break something into parts and explain how the parts connect or affect each other.
11. Suggest : Give a possible answer, solution, or explanation.
12. Calculate: Work out a numerical answer and show your working.
13. Identify: Choose or name the correct answer from the options given.

[ELL/LIT PAPER 2]
specific things to take note before your prelims
1. dissect the question before choosing it
identify:
• the command word: “compare”, “discuss”, “evaluate”, “to what extent”
• the central concept: power, truth, freedom, identity, conflict
• the specific focus: characters, setting, transformation, authorial choices
• any important qualifiers: “significance”, “changes”
2. test the question against both works
before committing, make sure you can produce:
• three distinct comparative arguments from the quotes and ideas you have prepared
• authorial choices that you have prepared to analyse
• meaningful similarities and differences in both form and theme
don’t choose a question just because it suits one text well
3. analyse evidence in layers
after introducing and contextualising your evidence, explain:
• the authorial choice
• its immediate effect
• what it reveals about the character or situation
• its thematic significance within the work
• how it answers the question
this is meant to function as a guiding structure for paper 2 essays. spend 5-10 minutes planning your comparative claims and comparisons after the 5min reading time.
if anyone has queries regarding any aspect of langlit/lit (paper 1 or 2) feel free to drop a dm 😉👍
Langlit/Lit (SL/HL)Paper 2 structure (Introduction) - define key terms and outline the perimeters of your essay - contextualise how the theme seen in each text - main claim that connects the 2 texts (Body 1) - Comparative claim 1 - how it is shown in text A (Body 2) - how it is shown in text B - comparison (doesn’t have to be long, 4-5 lines is sufficient) (Body 3) - Comparative claim 2 - how it is shown in text A (Body 4) - how it is shown in text B - comparison (Conclusion) - make an insightful comment and assessment of the two texts with regard to the question demands - consider implications
also we would like apologise in advance for the bots infiltrating the channel. please ignore them 😭😭😭
[CHECK-IN] how’s prelims (revisions) going for everyone?
Hi guys! ‼️Here’s an interactive page i made with three IB approved texts: Medea, Streetcar named Desire, and Woman at Point Zero.
If you’re from ACSI, this will
particularly be beneficial for you guys since these are the prescribed texts from your school. More versions coming up soon for other texts so stay tuned! 👍
And if anyone has any feedback or questions,
feel free to leave a comment or dm myself or our admins ❤️
Hello! If there are any acsi students here that could let me know what texts you guys are studying for langlit/lit paper 2, do PM me or drop a comment 🙂 I'm in the midst of trying to compile a set of notes for the IB schools right now. If you're from another IB school aside from SJI & ACSI feel free to drop a comment or a text too!

Hi everyone! Here is a ib biology website, Noteworthy Science, that covers a lot of very useful things! This is from rly nice biology notes to EE & IA Guides wirtten by the author of the website! The website also includes flashcards, revision material and links to more useful websites (more ib biology content, exploration sides and more)! Hope this helps!!
Note: The website also includes IGCSE content for thos who need it/is interested!

Hello muggers 🩷 I know prelims are ramping up for all those taking major exams this year, and so i’d like to impart this reminder with you all:
if you weren’t ready, you wouldn’t have the opportunity and if you weren’t capable, you wouldn’t have the desire.
You can do this! I believe in all of you 👍
