As a teacher here on Verbling, I mostly work with students who are preparing the IELTS exam. The writing tasks are an important part of the exam. It would be great to have more booking options for students. On many occasions I have students who just want writing corrections done and do not want a video lesson. It would be interesting to have a 30 min session available to the students (not a trial) that I could use to correct their writing tasks. I hope you will consider this!
