hi, my dad wants to sign me up for the summer camp at mandarin and i want to know if you actually learn anything there or is it just like drop-in badminton? i may sign up for 4 weeks and i want to know if its actually worth the money. im a beginner (i think) so would the camp help me improve? and if i sign up for the 2 beginner camps, would they be teaching me the same things? thanks.
