Section 300, Murder and Abetment kuch kaha, kuch nahi, Main confused hoon

Maine read kiya hai kya IPC mein abetment ko section 300 se juda hai ya alag? Yeh clear nahi hai ke kaise hua kuch isme, especially abetment of guilt se. Isme to mention kiya hai ki section 303 ka case woh hain jo bhee direct involvement ke saath murder kar sakate hain, par kya section 300 mein bhee abetment karna hai kya? Aur kya iska relation abetment of guilt se related hai? Jab tum log mock tests dete ho, I'm at my shift, aur bas ek hour ka time hai question solve karne ka. Please kuch clarify karein.
