The mathematics of HL is almost the most difficult of all IB HL. Ordinary universities don't need to study some science majors, such as engineering, so don't choose this easily. This is complicated and time-consuming.

Back to the topic, HL's economy is really not difficult. What you said about poor writing ability is not a big problem, as long as you have the ability to understand. You will read a lot about extracurricular reading, which can improve your writing method and ability. His three IA articles are only 750 words at most, unlike the 2000 words in history. Besides his development prospects, if you want to choose business, you must take this course, which is very important.

Let's talk about chemistry My HL is ok, similar to that in China. You can get a good grade by reading the things in domestic high schools for three years. It values the ability of independent research and creation, and IA designs and implements experiments by itself. So if you want to read more and know what you are interested in, you can ask about relevant experiments in China and get high marks.

I'm not studying HL biology, so I can't say.

I hope it helps you. Come on, IB student! !
