I did level 2 and im finishing off my first year of level 3, in my opinion its a great course to be in and really teaches you more about animals in general, although it all depends on the college and the facilities they provide, in my college, the teaching generally consists of; husbandry and care of animals (grooming, diet etc), health and disease of animals (covers anything and everything related to the animals' body), welfare and ethics (things about how animals are treated, animal behaviour and what it means as well as work experience, as it is a requirement over here.
I loveeeee the course, so i'll speak from experience and tell you about the pros and cons of the course...
Pros:
You literally meet the nicest and sweetest people in the world! i mean you're essentially working with people that love animals
You get to work with SO many animals, here are some i've worked with (again, depends on the college you're in)
Mammals: Rabbits, guinea pigs, sugar gliders, mice (normal and pygmy), hamsters, degus, gerbils, rats, hedgehods.
Reptiles: Bearded dragons, basilisks, geckos, skink, tortoises, chameleons, and snakes (pythons & cornsnakes)
Birds: Lorikeets, zebra finches, & lovebirds.
Inverts: Stick insects, tarantulas, scorpions, millipede (ew i know), cockroaches, snails, crabs, turtles and toads
I also often work with marmosets ^ they are adorable lil things
Cons:
It is probably one of the lowest paid industries to work in...like im talking minimum wage...so uni would be one of the only ways to get paid more but you can always do some research on that!
Assignment workload and time completion period is crazyyy...i dont mean to freak you out but ive got 4 assignments due in the next 2 weeks and each of them are around 30 pages long
So the course does include a lot of practical and theory sessions, although the practicals are rare unless pictures are required for the assignment/unit.
If you have any more questions feel free to ask!
