My favourite subject this term(in the university)

I'm studying engineering of food, the first semester and this have 6 subjects(chemistry, chemical laboratory techniques, english, mechanics, introduction of calculus) but I come from other university and for this I don't have mechanics.
And my favourite subject this term is chemical laboratory techniques.
In this subject in classes we do many chemical experiments related to basic chemistry, we have 40 minutes to theoretical classes and 3 hours 30 minutes to practical classes(the classes mostly practical), and I like practical classes because: all the theory is proven in the lab and I'm interesting for the labour field of research of food and I created a new and innovation food so that later it reach in the big markets and for this I need learn and know the laboratory very well and this subject is a introduction and beginning to this.
The teachers in the laboratory have doctorates, magistrates, books and publications and they are a inspiration for me, because I want to become like them.
I love this subject but have a only problem, we are in the class 30-35 students and in my opinion we are many students and they don't give personalised classes.
