Foundation degree at 43?

Do I go ahead and enrol for this degree? Im a little scared incase its out of my depth. Managed nvq 2 and 3 recently, love my job in the pre school, enjoy going on short training courses and workshops keeping up to date on early years. Ive also just completed senco training. Just wanting to no if anyone else had doubts to begin with but has since started the degree and is enjoying the work load. I think im frightened incase i will find it such a huge jump course work load from the nvqs. Also where can the degree take you work wise? Im 43 and sometimes im thinking youve achived a lot doing the level 3.(didnt think i could do that either, completed it in 7 months) All replys are very welcome.....thankyou lou x
