PHP Core issue fixes and changes to Custom Build PHP Core Website

Following changes and fixes are required to be fixed 1) RESUME LATER and REVIEW INCORRECT/ REVIEW DIFFICULT items in report are slow. They need to be made instantaneous so when user click on them it instantly take to report or to the review items. 2) Report is not showing correct values. It needs to be fixed in summary section as well as in domain performance section 3) Difficult marked items not showing in report. And when clicked on Review Difficult then it shows blank. When coming back to report, entire report now is shown with nil values. 4) RESUME TEST button is very slow. It needs to be modified to be instantaneous 5) TEST REPORT button is very slow. It needs to be modified to be instantaneous 6) SEE REPORT & RESUME TEST buttons in MENU -> MY ACCOUNT -> TEST HISTORY are extremely slow. They need to be fixed to be instantaneous 7) There should be a way for user to END TEST (the way currently user can RESUME TEST later without ending it). (Its simple by marking questions of that test with Test Completed flag. but user should have a button to END TEST from report). (Like in test report the EXIT button should be converted to EXIT TO RESUME LATER. And new button added END TEST & EXIT. Need to get this fixed in a day. Please provide fixed price quote.
