This is a good personal statement, offering range and depth. It is likely that
you might need to shorten it a little if it is to fit into the personal statement
box so check that out.
Some minor points to attend to:
1. Having thoroughly enjoyed the academic study of 'A' level History, I now
aspire to complement and diversify my enthusiasm for History with the influence

2. my in- depth [in-depth]
3. with their reading to approve [improve?] their literacy levels
4. my self- confidence [my self-confidence]
Content and expression generally good and appropriate. Just make sure it's
not too long.
I will send this on to the History Department, so that they can add their comments
(I am an English teacher).
