Mnemonic for bravais lattices (if someone's looking for it lol)
Class - Cubic
Test - Tetragonal
Of - Orthorhombic
History - Hexagonal
Takes/Requires - Trigonal/Rhombohedral
More - Monoclinic
Time - Triclinic

*Class Test Of History Takes/Requires More Time*


Edit: Thanks for all the responses but I'm a girl not a dude 🥲 And it's fine if you can remember it with some other mnemonic, I'm just giving you another one in case you remember this last moment 🫠
