Reading Comprehension

Hello friends
I am aware of the RC passages and questions. I am also aware of a general strategy of tackling the few question types: main idea, supporting ideas, inference, tone..etc. I have also given my first CAT. Now, I'm looking for an increase in RC. I have the MGMAT course material but I haven't gone through it. I searched on this blog and tried a couple of strategies suggested by people.

- I tried memorising the structure
- Then I tried writing the crux of each para in 10 words
- I tried making diagrams connecting one node to another with their attributes and relationships (I am a s/w engg so this comes naturaly to me)

All the above strategies didn't work for me. The first was difficult, the second was confusing for difficult passages(also I was confused whether crux refers to semantics or structure), the third was very time consuming as I ended up making diagrams capturing the whole passage again. Then I came up with my own. I am attaching the strategy as it's a little lengthy. Please let me know if somebody tries this and finds any luck. I welcome any comments.

Best Regards
