Chemistry compartment checking

In the exam I have marked 7 mcq's correct and I am getting like 18-19marks from rest of the paper which makes my total around 25 and in the rest of questions i have also tried to mention some relevant words and I have also tried to mention the key words like d-d transition, silver mirror formation,presence of unpaired electrons in my answers ,so in case of very strict checking will they fail or I am completely safe ?
