Firstly big ups to Mr Lee @le_evy , you nailed this coarse. I was really excited to start this coarse , it had its ups and downs. Yooohhh !!! There was a topic where i was like yerrr Jesus God me help me specifically( 2D AND 3D triangles) , to round up everything this coarse helped me strengthen my weaknesses on trig . And Mr Lee you are the best. Thanks alot
