About the 'swipe' password
Some students are in the habit of creating a password by running their finger along a row of keys on the keyboard. For example, they'll hit the Z key and swipe their finger along the keyboard to the ? key, creating the password zxcvbnm,./ .
Don't do this!
It's not clever or cool, it's risky! As soon as someone sees you swipe your finger along the keyboard, they have a very good idea of what your password is. Even if you don't swipe all the keys in a row, or pick a different row, or turn on caps-lock, you have given everyone around you enough clues to figure out what your password is.
Don't be lazy when choosing a password. Put in some effort to make it memorable for you but difficult to guess. If you need help doing this, Google 'how to choose an easy to remember secure password' to learn some techniques for developing hard-to-crack passwords.
