Level 1: mixed practice
Each question is one of the six skills of Level 1: a bought call, a bought put, a sold call or put, a forward contract, open interest, or comparing two positions. As in an exam, you also have to choose the right rule. You master the skill when you get three right in a row, with at least one right answer for each of the six.
Mixed practice:
After a wrong answer, the lesson for it is one click away: call, put, selling an option, forward contract, open interest and comparing positions.
Concept check: true or false
Exams also ask about ideas, with no numbers. Decide whether each statement is true or false, and you will see why after each answer.
