So i left the college because I didn't like the major, and now idk what to do. the college i left didn't have light or water as it was located in the top of the hills. i came back home for entrance exam, but i only have one month now for preparation, i m just tired and at the saturation point. i feel like disappointment for my parents. they are really really working so hard for my studies (12+ hours everyday), and it's makes me feel so guilty. so maybe anyone can suggest some study tips or any life tips?
