| The thing that I see a lot when it comes to goofy mistakes has to do with the chain rule. Some people always forget it (a sure ticket to a 1), while other people only sometimes forget it.
The other thing I would do is take your time through the review process. You can work on getting faster later, but if it takes you fifteen minutes to get through part (a) and make sure you make no mistakes, then you should take fifteen minutes now. Work on getting things right at the moment would be my advice. |
