Johnathan, welcome to the network!
To add to the information that Ken provided, VFR altitudes are generally IFR altitudes plus 500'
(1) On a magnetic course of zero degrees through 179 degrees, any odd thousand foot MSL altitude +500 feet (such as 3,500, 5,500, or 7,500); or
(2) On a magnetic course of 180 degrees through 359 degrees, any even thousand foot MSL altitude +500 feet (such as 4,500, 6,500, or 8,500).
IFR Altitudes are as above but without the 500' additions, and increase to 2000' at flight level 410 (41,000').
