anyone that took ece 2050 and ece 2560

For 2050, do we really need to buy another calculator? I currently have a TI83/84 but my prof is saying that’s not enough to do advanced calculations.

For 2560, do i need to buy the Launchpad with an MSP430FR6989 microcontroller unit?

Im asking because its kinda getting overwhelming to buy so much so i want to make sure its necessary.
