I request to one of my dears here, who has always been looking things to generate lame excuses to skip studies. Nevertheless, guys just speed up in your preparation with your targeted time-frame and time table to come up with a good result, as it is little time now. Don't waste your time in such fragile news, which will take ages to get implemented likely.

I wish you all the best.
