1. CORPS not CORE
   For instance, it is INFANTRY CORPS not INFANTRY CORE;
   There is nothing like Provost CORE or Ex Boys CORE.
2. PROVOST not PROSE
   This has assumed a worrisome dimension. We need to use the right words to avoid confusing ourselves please.
3. (GOOD) MORNING SIR not MONSUB not ONSUB.

This is standard greeting and not "NMS GREETING". Getting used to it can embarrass you when discussing with others outside the school. 

It is important that we take these and more corrections seriously so that we can communicate effectively.

Thank you.
