Thank you all,
My ranking jumped after i posted the issue, looks like it has been resolved.
However i feel the points have been not added for the recent task that i completed.
My experience points before i completed the last task “Install and Configure Web Application” - 18930
Then i completed a review (75 points) and a task (75 points) = total 150
my current points total = 19055 when it is should it 19080. This may be small difference but there may be others whose difference may be bigger.
