This document last updated: 27 September 2011.
These pages provide comments on past exam papers for the Economics Tripos Part I Paper 3 (Quantitative Methods in Economics). Where there is no comment for a question, it probably means I've not yet had a go at it, or that it doesn't exist. Make sure you check my corrections page too.
Key:
OK: at least broadly OK
OK(D): Question OK but we've already done it during the year
N/A: No longer on syllabus, as I understand it
OK? or ?: Problem (small or large): you might prefer to avoid this
question
Part 1 Paper 3 2003- (covers both maths and statistics)
| 2003 | 2004 | 2005 | 2006 | 2007 | |

| A5 | OK | OK | OK | OK (Good) | OK |
| A6 | OK | OK | OK | OK | OK |
| B1 | OK | OK except (a) a bit confusing | OK but long | OK | OK except question should say G = G_bar - tY, not G = G_bar + tY |
| B2 | OK | OK (relatively easy) | Tedious(D) | OK (Bit tedious as usual) | OK except the very last bit, which is beyond Year1 syllabus |
| C1 | OK | OK | OK | OK | OK (c) and (d) not easy |
| C2 | OK(D) | OK (Good) | OK (bit tedious) | OK | OK but time-consuming |

| D4 | (c)? |
| 2008 | 2009 | ||||
| A1 | Hard for section A | (a) quite hard (b) horrendous | |||
| A2 | OK | OK | |||

| A4 | OK | Weird and confusing | |||
| A5 | OK | ||||
| A6 | OK | ||||
| B1 | Seems to have an error in that the determinant (part (b)) could be positive or negative | OK | |||
| B2 | Interesting but long, error-prone and (e) unclear | (a)-(c) OK though error-prone; (d) hard | |||
| C1 | OK | OK - slightly unusual | |||

| C4 | Unclear | OK | |||
| C5 | OK (quick) | ||||
| C6 | OK | ||||
| C7 | |||||
| D1 | OK (quick for section D) | OK except too long and not clear if one has to test "assumption" of independence in (c)(i) | |||
| D2 | Long and (d), (e), (f) unclear | OK | |||
| D3 | |||||
| D4 |
| 2010 | 2011 | ||||
| A1 | (b) is badly-worded | OK (Good) | |||
| A2 | OK (fairly easy) | Useful though (ii) could be long or short | |||
| A3 | OK (fairly easy) | OK (Good) | |||
| A4 | OK (fairly easy) | OK - "proportionate" could be clearer | |||
| B5 | OK (very quick for section B) | OK but very error-prone | |||
| B6 | OK (very quick for section B) | OK though last bit unclear | |||
| C7 | OK | OK | |||
| C8 | OK | OK | |||
| C9 | OK | A bit contrived and confusing | |||
| C10 | OK | Hum | |||
| D11 | Absurdly long in (a); (b)(v) should say Q2 and Q3 | Time consuming and confusing | |||
| D12 | OK, though much quicker than D11 | OK (Good if quick) - much shorter than D11 |
