Thank you sir. But actually I am talking about the marker colour which you are using during the time of teaching( jab aap samjha rahe ho tab matlab yellow for answer hain to fir jab aap yellow se hi tick krke samjha rahe ho to samajh nehi aa raha ki kaha tick kiya hain aapne). Otherwise all good.🙏🙏
