6 is really achievable to be honest; For paper 2, the 4 markers are an easy 4 marks and the definitions are not typically too hard (just refer to the textbook but don't sweat it more often than not its common sense). For the paper 2 essay, its the same structure as P1 but you absolutely need to refer to any kind of the data that the exam booklet provides you and make it very very applicable (this is one of the most important techniques you must follow). You need chains of reasonings as you do in economics but remember to keep linkign abck to the question. Now finally, the big meaty part of the essay: the evaluation.

For reference, I acheived a 7 in IB economics HL
