# How are the marking schemes to be used? (edexcel, ial) watch

1. I'm self studying biology, so I don't really have a teacher or a tutor to ask this from.
In the biology marking schemes, at least for the IAL ones ive done so far, there seems to be more points in the answer than the allocated marks, so should i get all the points or just the number of points corresponding to the mark correct, to get the full mark?
eg:

Any help is appreciated, thanks!

The reason there are more points is because there are multiple options. Put as many as they ask for in a question. The others are because some people will put perfectly valid answers that are slightly different.

E.g. if you were asked to "name one factor that affects photosynthesis". You could say TEMPERATURE, CO2 CONCENTRATION, LIGHT INTENSITY as the main ones. If you say any one, you get the mark, but all the others are correct so they have to put them in the mark scheme.

so... as many points as the allocated marks?
