Don't worry, Vinitkhicha1111, that actually sounds completely normal. You'll almost always see 4 RC passages on the actual GMAT, and they could appear pretty much anywhere on the verbal section. It's definitely irritating to get hit with a bunch of RC at the end of the test, so you might want to keep track of how many passages you've seen so that you aren't blindsided by a heavy dose of RC when you're not expecting it. The balance of SC and CR also sounds right -- there's usually more SC than CR, though it's possible that you'll see 12 or 13 CR questions instead of 11.
Keep in mind that mock GMAT exams from test-prep companies aren't always an accurate reflection of the real exam. The GMATPrep tests use an algorithm that is very similar to that of the actual test, so it's likely that your GMATPrep test was accurate, and some of the other practice GMATs you've taken could be a little bit off.
I hope this helps!
