Yes, it is very much possible! Make sure you put in the effort to study and revise a LOT for your mocks so you can concentrate on essay writing closer to the exam (i'm assuming you have mocks soon, because I do too?)
Get out the key quotations, I'm doing songs of experience and innocence too, so the most important out of that is like "mind forge'd manacles" "dews of the night" (these might mean nothing to you if you're not doing the same ones as I am)
And also, don't forget to add in context - e.g Blake was a dissenter, so he despised the documentation of the church and state, but believed entirely in the bible as society makes itself corrupt blah blah you probably know this,
as well as alternative readings (i just go online and steal people's stuff and write it in my exam as my own alternative reading :P).
