Question

Wether the sentences are correct
I received a master's of science degree      --- I think it should be " I received a master degree of science"

I may use my training in computer sciences to solve engineering problems.-- --what I think is "  I may use my trained computer science skills to solve engineering problems. "

which one is right ?  computer sciences or computer science

Answer

It's always a master's degree. Since the degree belongs to the master (i.e. the graduate).

For the second question, it depends. There's "Computer Science" which is specific, or computer sciences which refers to a group of difference disciplines that are related. However, the first sentence you give is correct, "trained computer science" is the incorrect verb conjugation for train.
