1. ## IB biology SL or HL?

If you want to do something science-y or medical in university, do biology HL. It is a really interesting syllabus mostly for those who are biology inclined.
2. ## Do you get an ATAR at an IB school?!

Yes, the score you get out of 45 will be converted to an ATAR according to a pre-determined conversion system, which can usually be found somewhere online during your final year of school. Can usually find this by googling 'IB to ATAR conversion 2019', for example.

4. ## Sleeping hours

Never understood the necessity to sacrifice sleep to get work done. You should be able to finish all assignments, have time to play sport/socialize and still get 8 hours of sleep nightly. I cannot focus, study or retain any information without 8 hours of sleep, I simply feel terrible. Everyone has a different situation and should organize their schedule accordingly of course, but there is always a solution and certainly 4 hours is insufficient.
5. ## Extended Essay + TOK Presentation = Only 3 Points?

Your ToK essay is also included in that combination. Small amount of points that could eventually be the difference in university admissions. They are considered priceless in that EE/ToK define the IB diploma programme; other educational systems don't insist on you writing a lengthy academic essay nor studying the theory of knowledge.
6. ## Chi Square Question?

Calculating p-values manually involves finding the probability that you are outside the critical value, for a given significance level (usually 0.05). Even calculating it manually requires either the tables or a calculator, so a calculator should be fine for this task.
7. ## Enthalpy exercise help please

Check your units on the calculation of Q = mc∆T for the system, making sure they are consistent. Q = 100 g * 4.18 J/g*K * 35 K = 14,630 J = 14.630 kJ. Then calculate the amount of ethanol burned in moles. Enthalpy change of combustion is then kJ/mol, the two above values once you calculate the moles. You should get an answer around -378 kJ/mol I believe.

My username is the first half of my given name and also my nickname.
9. ## IB is not fair.

The IB doesn't expect Shakespearean English in your ToK essay. I'm a native speaker and I'd say my essay flowed pretty comfortably, but I ended up scraping a C for my essay. It's more your ideas/analysis and how applicable they are to the question. Judging from your opening post it seems you can express yourself in writing quite well!
10. ## Getting a 7 in Math HL

Get your hands on the IB questionbank which can be found hovering around the Interwebs, a quick google search should get the job done.
11. ## What is your religious affiliation?

Born into an Islamic household and subsequently raised with the basic teachings. Parents were never really strict on me religiously, however, I now consider myself an ardent and devout Muslim. The more I grow older and delve deeper into my faith and other religions the more I am convinced that what I am following is indeed the truth. That's how religion/faith should be in my opinion; allowing the individual to explore and be convinced of the truth themselves, without referring to the bias that infiltrates our televisions and media.
12. ## Which of the core topics is the most difficult? - Opinions

Row reduction of matrices in the old syllabus was always annoying, especially when you take the wrong first few steps and are stuck in a mess. Induction proofs often were tricky, the proof in my N12 exam in P1 gave me nightmares. The fact that I still remember the question distinctly speaks volumes.
13. ## Factors affecting enzyme activity - Biology HL IA

Received a 7 for this IA.
