Ok, I always was a procrastinator and had reasonable grades. I always thought that if I tried harder (I had a lot of free time), I'd have better grades in the college or in the bachelor's degree. However, I'm now in a master of science and I'm having a lot of difficulties that I never experienced before.. Was it because I never went deeper in the issues I was studying? Something, reading a scientific paper I take too loooonng to understand it, and I work daily but am always behind.. Have you ever felt like this? Is it something in the way I study? Plus, everything seems so confusing to me.. My question is: How can I be more efficient? What should I do?
