it totally depends really on what you want to do.
If you really want to teach and can see yourself just doing that as a job for 40+ years, then its great. however, i have heard that it is very stressful, long days and all at uni along with placements.
However, there is ed studies, which is better than it first sounds, as you learn more about the education side of things rather than learning how to teach maths and english etc. it will also open you up to more carrier choices later on if you chose not to teach your whole working life. If you still want to teach, you will be able to go on and do a PGCE to go on and teach.
hope this has answered your questions and just as an FYI im going to do Ed studies next year after being rejected for the teaching and my plan is to go an do a PGCE after this.
