Hi,
Unfortunately, I'm not in Singapore but I can help you online via shared screen. I am currently an MBA student at Columbia University in New York. During my 6 years of private equity and investment banking experience, I have developed more than 100 comprehensive financial models across a wide range of industries.
Last semester, I was also tutoring my classmates for the Accounting course, in which I got the highest score, so I am comfortable with explaining the basics even you are not familiar at all.
I am free this Saturday, Sunday and Monday from 9am New York time. You can pick one of these days at your convenience for a 4-5 hours session.
Kind regards,
Ege
