I took Maths HL (4), English A HL (5), History of the America's HL (4), and Econ HL (5). Physics SL (6) and Spanish B SL (5) were my other two classes. Econ HL is so similar to SL that you can probably take either interchangeably. The two classes are near-identical. Paper 3 is basic mathematics knowledge, not economics. Hl math is a struggle.
Most people are stuck on that contradiction question so I thought I'd share this solution. This is how to do the contradiction question -Assume a root k. Plug it into the cubic. Factorise out the 2 to give 2 (k^3 + 3k^2) + 1. From the plus one, it will always be odd. Hence impossible for it to be 0.
Mock Exam Set 1 - Paper 2. On September 1st, an orchard commences the process of harvesting 36 36 hectares of apple trees. At the end of September 4th, there were 30 30 hectares remaining to be harvested, and at the end of September 8th, there were 24 24 hectares remaining. Assuming that the number of hectares harvested each day is constant
STEP 2: Find two results which contradict each other. Use algebra to help with this. Consider how a contradiction might arise. For example: ½ a is positive and it is smaller than a which contradicts that a was the smallest positive number. STEP 3: Explain why the original statement is true. In your explanation mention:

These exams are notorious for high-grade boundary (98+% for students in there to get into a worldwide known university (compared to IB's lenient 80% grade boundary), much shorter time for an exam, and the easiest question is as tricky as the hardest IB math questions), Due to the brutality of these gulag exams, students there found every way R6Z1E. 162 420 306 154 218 282 294 264 496
