1 Practice more. 2  Practice early for your maths test, for example practice one or two weeks before the exam and that will give you time to practice math problems everyday. 3  Don't have a melt down if you don't do as well as you hoped.4  There is always next time to do even better. 5  Don't worry if you can't resolve a problem.

A monomer is a single structure and has low moleculer weight, while a polymer consists of several monomers and appears like plastic such as shellac and varnish.A polymer has higher molecular weight. Polymers don't always look like plastic--wood and cotton are both polymers. Rubber is also a polymer.
What's the difference between plastics and polymers and elastomers? Polymer is the chemical term for a long chain molecule often made of repeating monomer chemical units. Synthetic plastics, DNA, cellulose from wood and other natural products are all polymers.hat's the difference between plastics and polymers and elastomers?
