Correct this entry?  OK!  There isn't much to correct, it's well written but the idiomatic expression "on one hand, on the other hand" has a meaning that you are missing.  You are using it to mean additional or further, whereas its correct meaning is more converse or opposing.  On one hand was the door to the lady and on the other hand was the door to the tiger.  I have lots of preparing for the test to do and _____ lots of translation work to do.  Can you supply a good expression in the blank?  You want one that means only <test prep> but also <translation work>.  There are many to choose from; I did a quick search and found this:
