These days ,it observed that many parents are in favor of physical punishment to discipline their children but its an issue of society thatwhether its bad or good or badbut i am partially agree in my point of view .
You should take your opinion to a new sentence; otherwise this sentence would be too lengthy and its flow would be affected.
Also, in the modern society, especially in the West, the trend is more to reject physical punishments. So, I think it is not very prudent to say many parents favor that. After all it is very likely that your essay will be evaluated by someone from the West who is not in its favor :D
first First and for the most thing is throughoutthat punishment in schools leads to good performance.
Is that so? You have not supported this reason with an example :(
