The more you practice, the easier critical reasoning becomes.
As you practice, learn to recognize the most common assumptions made in arguments:
-- that X caused Y
-- that a plan, when implemented, will achieve its goal
-- that X is the same as Y
-- that one example means it's true for all
-- that a rise/decrease in percentage proves a rise/decrease in the actual number
-- that a rise/decrease in an average proves a rise/decrease in the actual number
You need to understand how to strengthen and weaken each of these kinds of arguments.
For example, if an argument assumes that X caused Y, to weaken the argument we'd look for for an answer choice that shows that something else caused Y, or that the relationship was reversed, that Y caused X.
Once you to start to recognize how the GMAT tends to strengthen and weaken these types of arguments, you'll find it easier to spot the correct answer, because you'll know what to look for when you examine the answer choices.
Good luck!
