You can access a full-screen TTY session by holding down the Ctrl+Alt keys, and pressing one of the function keys. Ctrl+Alt+F3 will bring up the login prompt of tty3. If you log in and issue the tty command, you'll see you are connected to /dev/tty3.
Explanation:
- tty2 is short for teletype, but it's more popularly known as terminal.
- It's basically a device (implemented in software nowadays) that allows you to interact with the system by passing on the data (you input) to the system, and displaying the output produced by the system
- You can either : press ctrl+alt+F7 Or run the command startx if the above commands do not work.
- The tty command of terminal basically prints the file name of the terminal connected to standard input.
- In Linux, there is a pseudo-teletype multiplexor which handles the connections from all of the terminal window pseudo-teletypes (PTS). The multiplexor is the master, and the PTS are the slaves.
- The multiplexor is addressed by the kernel through the device file located at /dev/ptmx.
- The -s (silent) option causes tty to generate no output.

He must score 86 or more in the fourth test to get and A
Explanation:
The needed score can be found with this equation

x = 360 - 274
= 86
x represents the fourth score, the sum of the four scores must be up-to 360 for the student to get an A
