Hi,

I am planning to retake TOEFL in near future.

In my last test, I thought i have done good in this part(Integrated essay).

But i got limited,I have reffered barron's writing essay book and pearson's template but i got low score in this part.

It will be helpful for me if i can get idea what should i need to consider now to improve my score.

I am new to this community and I hope I can improve my score because of the suggestions from seniors over here.
