well, no that's not what i meant. Actually the initial refusal letter is quite generic for all. Hence, it doesn't specify the exact reason of your denial. However, basis one's profile, it becomes easy to understand if the proposed course is a mismatch. Like, If I am a graduate in Science Steam, and opting for a commerce PG Diploma, it's very well understood to be a mismatch. However, as said earlier, profile needs to be discussed, and the initial refusal letter is generic one being issued to all denials. In very few cases, they specifically mention the reason otherwise students are advised to file for CAIPS to understand the exact reason of denial.
