Dear rabiaa
First of all, I'd like to thank you for watching the video and I want to tell you that I'm not a man
Then, about the mistake you have mentioned, I think you lack lot of reading. Because seeing my sentence as a wrong one , gives me the proof that you don't master grammar very well. It comes to my mind that famous song of Elvis Presley called ' If I can dream' where he uses this kind of structure
Next, you said :' ..... how about students?' but this is wrong. I had written ' what about students?'
Also, you said that this is one of my mistakes. Would you please mention them all
Thank you
