Hi Huekhiemtran,
Do not despair
. There can be many reasons for your score, from prep strategies to the proverbial bad day. The key is identifying how you prepped and to help identify the areas in which you could tweak your approach.
So a few important questions:
1. Did you take any practice tests before the real exam, and, if so, which ones and what were you scores?
2. How did you structure your practice sessions with
the Official Guide? For instance, did you ever do timed drills? Did you mix up question types?
3. When you missed questions how did you follow up on them?
4. How did you go about learning new concepts? How often did you apply what you learn to actual practice questions? Did you go back and review or did you always move on to new material?
I know this is quite the flurry of questions! However, knowing the answer to them will definitely help me figure out in which area you could improve.
Of course there is always the question of not how you used materials but which materials you used. The
OG is the bible of GMAT prep -at least for questions (explanations often are mystifying than illuminating). I haven't heard too much about the Kaplan on-line course so I can't speak to that. As far as the Holy Grail of prep goes in terms of learning fundamentals, nobody can beat
Manhattan GMAT.
If you are more disposed to video learning, I recommend
Magoosh. We have lesson videos covering all of the fundamentals and 700+ practice questions to help you apply the concepts you've learnt.
Anyhow, I'd love to get your responses to the questions above so I can provide a targeted plan to help you get the score you need.
Hope that was helpful
.
