A very embarrassing question, But how do I do CHEMICAL BONDING?

In 11th and 12th, I never understood the concepts. I just mugged up the formula or structures and went for mains. Now there's only 2 months remaining and I'm redoing all the chapters properly.

In 12th I started watching lectures from Mohit Tyagi ( Alok Sir) but it had 56 lectures and initial lectures had a lot of information (Thermodynamics, Inorganic chemistry). It felt like I'm just watching them and not getting anything. Long story short, I left that chapter altogether.

Whenever it was mentioned in organic, I just memorized the basic facts about hydribrization.

I gave up and tried reading the ncert. But it's written in such a bad manner that it's a waste to read it as a newbie.

TLDR- I failed to do chemical bonding. How do I clear my concepts?
