Thanks for your responses guys...A little more about my study history.
Firstly I haven't done maths since School which was 7.5 years ago (other than a stats course at University). I was actually pretty good at maths at school won a number of awards and stuff in junior high and late primary school. main problem is I basically taught my self for my senior high school years (I was home schooling) and I only ever taught myself the minimum to pass exams. As a result a lot of the concepts in GMAT courses are more of less new to me (even though I may have actually briefly half heartedly studied them before). Figuring how to solve a problem is something I am very talented at, the maths part I just haven't learnt and practised well enough (hopefully this makes sense).
Phase 1: I started GMAT study about 5 months ago, the first two months I was basically doing a several nights a week mostly doing
OG questions and some other diagnostic test and then getting my tutor to help me learn how to solve the questions. looking back it was a bad approach because 1. I just needed more maths practice, 2. I was never timing anything, 3. I wasn't spending enough time and eergy focusing on it.
After this I went to Europe for 3 and a half weeks visited bschools the wifey and I decided, yep we were actually going to do this and yep I actually needed to knuckle down and focus on the GMAT.
Phase 2: Came back from Europe and started working really hard. Started doing more questions, finially cottoned on to the idea I needed to learn the content and time questions. Did GMAT CAT 1 (incl AWA and IR): Score 660, Q 42 and V 39. Bought
Magoosh premium and started studying all the videos and doing questions to see if I could increase more accuracy and time per question. I got more accurate and faster so I was pretty happy with myself. Did some SC study as well. Retook the GMATprep CAT (same one and again doing AWA and IR) got 680, Q39 and V42 big problem was I didn't answer the last 7 or 8 questions on the quant at all (I have heard this has a penalty of around 1-0.75 points per question over an incorrect answer, not sure if this is true?). At this point I was pretty devastated because more quant score went backwards, read online about the impacts of not answering questions and felt a little better. Did some more
magoosh study (videos and questions). Did a quant only practice test on
Magoosh and got around Q42 (50-60% somewhere, can't recall the exact score). I then came to the conclusion that I had to take a more targeted approach and really drill down on specific weak areas and practice, practice, practice, especially more fundamentals then just GMAT questions.
Phase 3: Over the past 3 weeks or so I have been taking my kill weakness approach, done more diagnostic tests, found some more weaknesses, and started attacking them. Past week or two I have been focusing a lot on algebra, as I have notice my lack of consistency and speed here is affecting my success in heaps of different question types. I have not been as consistent and hard working because I had to do various job interviews and so on with the new job I just received an offer for. Had a few other problems with my wife being unwell and so on, so I just had to make the decision to take a step back unfortunately.
Hopefully that provides a little more clarity
