My experience has a tutor has helped me with learning and relearning. You learn everyday actually and there are changes that are made to the curriculum every time so being a tutor has helped in keeping me updated about the present curriculum and all.
I have also been able to help over 100 students achieve better grades particularly in the categories of Math and Biology both in their internal examinations and external examinations.
