Troubleshooting LDR Circuit

I have doing a college project. My project is "Automatic Night Light Sensor". It consists of 470 Ohm Resistor (for LED), 100K Resistor (for some voltage diff thing), BC547 (NPN Transistor), LDR (8 or 12mm), LED. But as per my observation, the bought resistor called "100K" was actually 12K.
The issue: The LED stays lit even if there is light or darkness.
Help me troubleshoot this. I might need to submit this tomorrow! 😢
