So I hired an
MGMAT tutor myself, and he was pretty awesome. I took the LSAT when in undergrad (dodged that bullet) and took a Kaplan classroom course, so that's my base for comparison. What's nice about having a tutor is that they can give you tips for specific problem-types that will really help you. When you do an online program or a classroom, you're accounting for the lowest common denominator and the lack of customization can definitely slow your studying down. I know in my LSAT classroom setting, we had some folks that really slowed down the pace and it could feel pretty inefficient.
That being said, there are plenty of people who self-study and do VERY well. I feel like the biggest things I learned from my tutor were essentially tricks to solving tougher 700+ level problems. Otherwise, you can get tons of great advice from this forum as well as from an online program. If you're disciplined and trust your googling abilities, you may not need a tutor, but if you can afford one and it will make you feel more comfortable, a tutor can be a GREAT resource.
It also gives you someone to brag to when you get your dream score!!

I am also based in Oregon and was planning to hire a Manhattan tutor. Actually I do have a 720 score with Q49 and V40 but I am hoping to improve it further as I am an Indian female applicant. Also because I ended up on the waitlist for multiple schools, so I am hoping to improve my candidacy with a better GMAT score.
I have been trying to hire a manhattan tutor but it seems that they don't have anyone in Oregon. So I was wondering if you took online sessions with a Manhattan tutor? Also what kind of package did you take? Anything about your experience with the lessons will help me.
