Q26 & Q27:
I just referred pay slip to the start period but if you are going to apply in December then claim period would be start from September 2005 to November 2006 (Evidence required of any of last 15 months). Mine is December 2005 to November 2006.
Q28 & Q31
A,B,C,D,E is not a band name. A,B....E are country codes (Check old HSMP guidance). You can take example of an IELTS bands, there are nine bands in IELTS (1 - 9). These bands shows your English skill. You can suppose General Training & Academic training as country code. Your IELTS test report shows that in certain training module you got certain band. Same like this in HSMP, you can say that in Country Code D you got 7,500+ band.
Q30:
You need to show your total 12 months gross income in your local currency (if you earned in your country, for abroad earning please see guidance). As I am going to show "Pakistan Rupees (PKR) 999,999/="
Think dear, why they are asking for band, code, country and income. They will put all these information on currency conversion websites and will check your result.
Kindly check
http://www.xe.com/ucc/ and check your country currency code, for India I think it is "India Rupees (INR)". Reason for that, provide them exact same currency conversion information where they will check your band.
Wish you good luck.
