I need help writing codes for 2 programs in Visual Basic 6.

The first one has to be done in the Select Case format and the second one has to be done in the Loop format.

1. Program the decision using Select Case statements. Write a program that request an exam score and assigns a letter grade with the scale 90-100(A), 80-89(B), 70-79(C), 60-69(D), 0-59(F).

2. A TV set is purchased with a loan of $563 to be paid off with five monthly payments of $116. The interest rate is 1 percent per month. Display a table giving the balance on the loan at the end of each month.
