This might sounds hilarious but I am currently reaching my last year of IB with a predicted grade of 28. I do realised that I haven't don't the amount of work required, but also decided to take physics, computer science, math aa and economics as HLs last year. Right now I have dropped my math aa to sl, but I am just carious if I would be able to have some improvements if I starting to do some work? is there still time available?
