How many marks for correct steps for a answer does icse give?

okay so today was math and it went WAY better than I had expected. I was expecting around 77-78 but I found some silly mistakes in calculations( like writing 2/10 simplified to 2/5 even though I know it's supposed to be 1/5 idk what I was thinking) uh so yeah taking into account all the silly mistakes the final answers to 2, 3 mark questions are uh wrong due to such minor mistakes (and i hate it obviously but nothing i can do now i guess) and also the reflection question in section B where i JUST HAD TO FORGET to draw lines and connect the points which I was supposed to.

so my question is can they give 2 marks out of 3 if simply the final answer is wrong AND THE METHOD AND STEPS ARE CORRECT? and also about the 4 mark graph how much will they cut for me simply forgetting to draw lines? please help I've been over this the whole day
