To tell the truth, I don't think math HL is difficult, which is far worse than that in China, but many people say that I am good at middle schools in China, so I feel this way. But I think China people are really good at math, no problem. Calculus certainly exists, and so does China. The most difficult thing in mathematics is the collection of mathematical works we have to do. I wrote more than 5000 words, 27 pages, which was very annoying, but it was quite exercise.
3. Senior one came before he finished reading, so he didn't study organic chemistry. The physical calculation here is super simple. What is difficult for me is the theory. I usually study chemistry, but I have a poor memory. Our chemistry teacher is very good. I don't think it's difficult to understand, but I have to learn something by heart. Others think chemistry is quite simple. I have a terrible memory. I have to work harder.
4. Geography, without calculation, is all reading and some memory, as well as understanding. I think it's quite difficult because my composition is not good and my memory is not good. Well, I think it is much better than history or psychology.
5. 7 points for each subject, and then the last 3 points are added by the scores of extended essay and tok. The 7-point algorithm of each subject is different, but each subject has internal assessment and external assessment.
6. It's Chinese, of course it's not difficult. Mandarin Chinese
7. If you teach English, you should write an additional paper on world literature for HL. Basically, HL can get 6 points and SL can get 7 points. Of course, I chose SL because my English is too poor.
