Answer:
False(conditionally)
Step-by-step explanation:
The teachers always wish that their students attain the highest possible grade in assignments and tests, but it is neither necessary nor mandatory that the teacher keep telling the students ways to obtain the highest grade. A teacher aims to make students learn new things, values and grow in life and not mere involving them in the race to stand first. Thus, the statement is false but there are times like the pre-exam period where they keep discussing the exam format and the answer writing techniques to get the best possible marks or grade in a question. Thus, the statement is false except for some cases.
