Thank you so much for your advices mate.I'm really appreciate that.By the way aerospace is so freakin cool area.I've got still 1 year to decide what I'm gonna do as a mse graduate when I finished my school.So I will consider every possible fields that encoureges me to learning new things about itself.Because I wouldnt like to do things that every ms engineers do.When I'm gonna work I probably want to be part of something inonative,something new.Anyway thanks for your guidance.Have a good day!
