Karna tried to take education from Drona(Shishou of both pandavas and kauravas),but he denied due to inferior lineage of Karna[actually even his was Kshatriya but no one except his(+some of the pandavas)mother knew about that].

Karna then took education from Drona's teacher-Parshurama, he taught him about most of the godly weapons and skills and even gave his bow VIJAYA to him, but this time Karna lied or the situation was like Parshurama thought he was a Brahmin(highest lineage/monk), after knowing the truth(nit exactly truth) he gave Karna a curse that he'll forget everything what he learned from him at the worse moment(idk this was the exact curse coz i dont remember much).

If only he was'nt binded by the innumerable curses his chariot wouldnt sink in the ground-so tried to lift it himself and at that time Arjuna made his move and killed Karna.
