SSC CGL Preparation | Admit Card, Syllabus, Result

IMPORTANT QUERIES ABOUT DV. Hello all, I have my cgl dv on the 18th and have some confusion. I will be very grateful for your help. 1)Is permanent address as filled in the application form verified? If yes, if I have a different permanent address in my Aadhar card can I change my permanent address with ssc to that one? Will it require any affidavit on stamp paper or attestation? 2)I passed class 10 in 2009 from ICSE. At that time the marksheet and pass certificate did not have "date of issue" mentioned on them. Will this cause a problem? 3)In my class 10 documents, my father's name has been spelt without a space between his first and middle name. As per the instruction in notice of exam in my ssc application I have filled his name as given in 10th marksheet and certificate. I have made "one and same person" affidavit for him, will that be enough or will this cause a problem? 4)My college only gives marks in CGPA and DGPA, not in percentage. At the time of application ssc required me to enter percentage so I gave the percentage which comes from the standard formula used by our university and companies that come to recruit. Will I need to show a percentage conversion certificate at the time of DV? Please, I am very worried and panicking regarding these. Any and all help would be appreciated.
