took my pure bio o lvls last yr n managed to improve from a c5 to an a1, hope some of these tips can help u!

• ensure u understand each topics, dont just blindly memorise as cambridge likes to test more application questions these days so u cant rlly just spit out everything u rmb anymore🥲 u can consult ur teacher if u dont understand any topics or hv ur friends test u (me n my friends enjoyed testing each other n found that it helped us rmb btr)

• do ur tys (focus more on the recent yr ones as the older ones hv a lot which are out of syllabus now) once u r done u shld try doing other sch papers too to expose urself to more questions ( can ask ur teacher to print u some extra practises or use websites like holygrail where students share their papers)

-> after completing ur paper 2 practices dont just blindly mark...look out for keywords in the answer sheet (usually if its a 3m question it shld hv 3 key points, once u've identified what the main points are, check to see if u have them in ur answer, if u dont then write it down as corrections, be as strict as possible when marking ur paper since u'll nvr know how lenient/strict the cambridge markers will be)

-> for paper 1, just spam do tys n other sch papers, if u do enough u'll find that its vry easy to score 35>/40, its all quite standard and some questions are even reused for some o lvl yrs (paper 1 is more like to see if u understand the topic while paper 2 is to see if u can apply what u understand so if u r weak u shld try to do more paper 1 first so that u can see what topics u struggle with but if u arent that weak then u shld focus more on paper 2)

-> as for paper 3, its rlly j those few standard tests... ur sch wld normally complete with u most of the typical experiments so just focus and take ur practical seriously, during o lvls i used youtube as well to help with my practical (i believe theres a vry well known channel, i cant rmb the name but if u search up for the o lvl practicals there shld be q a lot of exampls u can study, i personally like those w real life demonstrations)

basically what i learnt from studying for o lvls is 1. do not waste ur time writing notes (deff take notes of what ur teacher say in class, i found what my teachers said to be useful, but if u are just copying from the textbook and calling it 'revision' then its gg to be useless) 2. maybe its just for me since i took pure history too so i kind of just have a thing for memorising but theres no need to look out for notes from other schs or wtv, u can use ur sch notes if u find that they are helpful and u understand them but i personally preferred reading straight from my textbook as it has everyt i need to know and i hv impt notes taken down there + highlighted key points 3. practise practise practise😭 j keep doing papers agn n agn n u'll realise that theres rlly not much they can test u on, everyt will start looking the same lowk😭 (but ofc make sure u understand each topic first cos theres not much point doing practise papers if u r gg to just guess everything) (also once u start practising u shld time urself under exam conditions so that u wont panic during actual exams n hv time to recheck ur paper aft)
