Good morning, @hannahbae ...
Yes, you should be able to do this by way of a question group within your quiz. Create your question group in your quiz...indicating how many questions to choose (74 in your case) and the number of points per question (2.02 or 2.03 ... neither of which will get you exactly 150 points, so you may have to make one question slightly more or less points). Then, you'll need to put those questions within the question group.
- How do I create a quiz with a question group to randomize quiz questions?
- How do I reorder questions or question groups in a quiz?
I hope this will help in some way. Sing out if you have any other questions about this...thanks! Take care, stay safe, and be well.
