Question

I having eog (end of grade test) this week what sould i do to help me do good?

Answer 1

All the normal stuff, like get a good night's sleep and eat a good breakfast. But really, you should have been preparing for this the whole school year by listening and absorbing the information you needed to. If you did a good job with that, I see no reason why you shouldn't do well on your test.

Answer 2

Get a good night's rest.  Eat a good, healthy, filling (protein & carb) breakfast/lunch.  Relax.

If it's going to cover grammar & spelling, then you should know in your question you should have used "well", not good, Capitalized "I" and "EOG", and spelled "sould" as "should".  :-)
