## Quick tips for quantitative problem-solving

1. Solving problems tests your ability to apply** theoretical concepts.** Both abstract thinking and computation are required.

2. Most courses have only a few key concepts that will reappear in novel contexts. Look for the **“spiral of learning”**: identify and understand these concepts deeply.

3. **Organize** concepts to see connections, and improve recall.

4. Use a** systematic approach** to stay focused, isolate errors in logic or computation, and reduce the panic.

5. Read to **define** the question fully: what is known? unknown? asked for? what is the significance of each different part?

6. **Solve what you can** initially. Think about problems using the same concepts (Newton’s 2nd Law, complementarity in base- pairing, equilibrium and Le Chatelier’s principle, net asset) that may use similar methods of solution.

7. In class: pay attention to the steps the prof. follows (**the thought process**) in addition to the computations.

8. **Describe your thoughts** as you solve a problem. Monitor yourself: are you on task? Do you remember your purpose in doing “x”? What’s the next step?

9. Work with **a good problem solver** and compare your thought process to theirs.

10. Working in groups can be helpful to share ideas, but **do some of each problem type yourself**…exams are solo events!

11. **STOP** if you plug in an equation that has the exact variables as the problem. Focus on identifying concepts…not memorizing formula.

12. **STOP** if you try to use solutions from other problems that don’t apply. Focus on identifying underlying concepts first.

13. Set** time limits** for homework questions (20 minutes??) and get help if needed.

14. **Keep up** with the homework…this material is taught sequentially.

15. In labs: **relate experiment or process to problems in class.** Do specific equations describe phenomenon being observed in the lab?

16. **Check your work** using a different method, if possible.
