First of all, there are usually only two points. However, there are exceptions. If the college entrance examination was particularly difficult that year, the answer score would be improved for the sake of the harmony of scores. This is the case in 2009, with a lot of points. As long as you write the answer, you will only deduct two points.

If the process is different from the expression, it will be graded according to the completeness of the idea, which has little impact. I took math 146 in the college entrance examination this year, and there were 8 big questions with different answers, but there was no deduction.
