Comment on Parallel or Not
Can you please explain how
The important thing to
The important thing to recognize that the rule for parallel lines goes in BOTH directions. Here's what I mean.
IF the two lines are parallel, THEN we know that ∠e + ∠b = 180 degrees.
We can also say that, IF ∠e + ∠b = 180 degrees, THEN the two lines are parallel.

Can you explain this one , As
If ∠e = 60 and ∠b = 120, then
If ∠e = 60 and ∠b = 120, then the two lines are definitely parallel.
Notice that, if ∠e = 60, then ∠d = 120 (since angles on a line add to 180 degrees)
This means ∠d = ∠b
If ∠d = ∠b, then we can be certain that lines 1 and 2 are parallel.
Conversely, we can also say that, if lines 1 and 2 are parallel, then it must be the case that ∠d = ∠b

Does that help?

Okay make sense , thanks for
I have a question regarding
Will they be significantly impacting my admissions?
As far as I know, most
As far as I know, most admissions personnel don't seem to be placing a huge emphasis on AWA and IR.
Having said that, I suggest you watch all of the AWA videos (https://www.gmatprepnow.com/module/gmat-analytical-writing-assessment) just to get an idea of how to tackle that section on test day.
I also suggest that you check out the IR videos (https://www.gmatprepnow.com/module/gmat-integrated-reasoning). You'll find that the question types in the IR section are simply extensions/combinations of math and verbal concepts you're learning elsewhere in the course.
