Dear Wilbert,

The UEFI-and-BIOS systems dated May 2016 are 64-bit. These systems are 
*installed* systems (can be installed into USB sticks, SSDs, HDDs or 
memory cards, and works like a normal installed system).

If you intend to use the USB sticks also for installing systems into 
other computers, it might be a good idea to have live systems or 
persistent live systems. The Lubuntu 64-bit iso files can also boot in 
both BIOS and UEFI mode.

Is it possible that some student has a 32-bit computer? You can make 
persistent live systems with 32-bit Lubuntu, that can boot in both 
32-bit computers and 64-bit computers, and in both BIOS and UEFI mode. 
This is when you use the usb-pack-efi for booting.

So maybe you should make some master USB sticks just to check that they 
work for you, and maybe bring more than one configuration, even if I 
understand that the focus is on 64-bit systems.

It is much easier to find USB 3 pendrives with good performance among 
those with 16 GB. See this link and links from it for details about the 
data transfer speed of pendrives.
