Regardless of the subject, what is the correct structure? From all the samples I can see...I suppose you're expected to start and close the essay with similar ideas, something like...

In my opinion, potatoes are better than tomatoes because blablabla.....

in the first place........

Moreover.......

In conclusion, potatoes are better than tomatoes because of the reasons mentions above.

would that be a correct structure? Am I missing something??

Please, I've never written essays in the "American way" so I do need loads of help...!
