My talents are waisted I can't get into theatre?

What blackgrumpy cat said.

Oh, and dollofvoodoo - it's "your education," not "you're education."

Maybe continue you're education because it's wasted, not waisted.

In the UK the only way you'll ever get to be an actor is by getting A Level Drama, several years of basic training at acting, singing and dance, and loads of stage experience (and school stuff doesn't count) and then trying for a place at a top drama school.
The courses are for three years, full time, and they only take the very best. They're also very expensive.

Good luck!

Have you applied to one of the accredited drama schools? Are you already involved in amateur or youth theatre?

Look at the link which has good information for people like you.

There is no real value in doing "a course" in musical theatre. If the courses you are looking at are not at accredited drama schools that attract thousands at audition, you must question the standard of teaching and quality of training there.

This industry is just too competitive to think that you have a chance at a career without great training. How many schools have you auditioned for? Do you have experience to go with your self belief? Have you carefully researched all of your schooling options on the Drama Uk website? You will find that at good schools most of the first year places go to people with extensive experience/undergraduate degrees and are over twenty. About one third of places go to high school graduates thought to have unusual ability and a proven ongoing commitment to the performing arts.

I suspect you are underestimating the amount of knowledge and preparation it takes to secure a place at these schools. It is common for people to audition a few years in a row. It is expected that you will know your monologues and the plays they come from back to front. Agents are interested (and actively pursue) graduates from these schools because they know the students are talented, highly trained and industry ready.

Gaining a place is close to winning the acting lottery. If this does not happen immediately for you, I agree with the other contributors that you do youth theatre, more vocal training and dance lessons etc. Expect nothing for nothing and arm yourself with information about the profession you are trying to enter. Best of luck.
