do you have any advice on how to score 5s and 6s in IB biology? im anxious about the exam :/
To be completely honest, I also feel really anxious about the exam (legit feel like IB Biology will wreck our shit). I mean right now you still have time to study and revise last minute, so take a deep breath and go over all the information. It’s really memorization heavy, so I’d start revising most difficult things like physiology and molecular bio (but it depends what you struggle with the most tbh.)
Paper One: Another hella important thing to remember is that in P1 you technically have a 25% chance of picking the right answer on multiple choice. My teacher also went over this haha. You should definitely take your time to choose the right answer and you should go over your exam once you’ve completed it. Sometimes you think you got the right answer but it turns out you didn’t. Also sometimes it may seem like there are two right answers, you have to choose the MOST correct one. The problem with P1 is that the grade boundaries are super high, thats why it’s really easy to mess up on.
Paper Two: this one is also pretty hard and is worth more than your Paper one and paper three (around 34% of your final mark, where paper one and three are 20% each). When answering the questions, you can write multiple answers. For instance, give an example of a greenhouse gas. You can answer: methane, water vapour and CO2. As long as your answers don’t contradict themselves. For example if you write: In the krebs cycle of cell respiration Acetyl CoA combines with oxaloacetate to form citrate. Oxaloacetate does not use Acetyl CoA from the link reaction to make citrate (wrong). These statements contradict each other and you get no points if you do this.
Additionally, when you’re unsure about how to answer the long ass essay questions fully, write down everything you know about the topic. EVERYTHING. DNA replication? First start with enzymes, forgot some? Dont worry - mention complimentary base pairing, characteristics of replication etc (you should be mentioning these to begin with, but just write everything you think is relevant, even the small things.) But make sure its relevant but dont be afraid to word vomit when you don’t know the answer. BUT be mindful of the time!!! You have to answer A LOT in the paper (i usually run out of time fast so it’s something i gotta work on too).
Paper three: Just be careful to read the instructions!!! Seriously, many people last year thought they didn’t need to answer a whole section, and guess what! They did, and if they read the instructions more carefully they would know this!!! You have to answer a bunch of questions before you start your option. Section A is the questions EVERYONE must do, section B of the exam is the options you choose from ONCE you’ve completed section A. This apparently was a huge deal because people thought they didn’t need to answer section A. Example: if you’re doing option C, you will first answer all of SECTION A, and then proceed to Section B, where you choose OPTION C.
Hope this helps! :) and good luck!
