I think you know where you stand with regard to GPA and GMAT and age. They are all public information from USnews. And yes, your GMAT is on the low side esp. in the V side. School will have a hard time taking someone with V being so low accompany by years of Quant jobs.
2. I plan not to include my education in Econ & Marketing in the application due to the GPA is low because the grading is different from normal GPA grading. Should I or should I not include them in the apps?
School will normalize your GPA and you should disclose them. In fact, in the application, its a violating of ethnic code for not disclosing. Of course, you yourself can be the judge of what is ethnical or not but be forewarned that there is a third-party verification process once admitted for most schools.
3. Is organizing the anti-governemnt protest a good or bad thing?
It is a good thing. Put it in.
4. Is too much WE is good or bad things?
Good if its <8 years and bad if its >8 years
