hi im not new to mining~
Welcome here! You have been studying for nearly two years? What subject? Cause with your computer specs, mining bitcoin "properly" is as useless as trying to empty the ocean with a spoon.
If you actually wanna mine coins, read up on ASIC rigs. But also think about just buying bitcoins instead, cause electricity aint free and mining may not pay off now.
Im no expert though and just my thoughts.
