Having experience of more than 10 years is good enough to coach my students. Currently, I am working as an active supervisor of ACCA students. In my career, I helped students in financial accounting, management accounting, cost accounting, financial reporting, taxation, and audit. I also helped students publish their articles or papers in good journals. I also helped students with thesis and objective writing.
