And it's a wrap.

Done with Geometry Theory. Got 38/42 correct in Kaplan book's practice sets. 3 questions - very silly mistakes. 1 question - although easy, it had a particular method to solve it. It's definitely a CP. Will post it soon.

Now starting off with Standard Deviation.

How To Wrap Up The Geometry Theory Module Perfectly

Geometry theory from OG - check.

Geometry theory from GMATClub's Math book - check.

Go through FCs to drill the formulae into your brain - partially done.

Geometry theory from Kaplan - pending.

Action Plan (from BTG's 60-Day Study Guide: Day 15)

To Do:

• In Kaplan's GMAT 2010-2011 Premier with CD-ROM:
• Read the section on Lines and Angles (p. 293-295)
• Answer questions 1, 3 and 4 on the Lines and Angles Practice Set (p. 296-297)
• Read the section on Triangles (p. 299-404)
• Complete the Triangles Practice Set (p. 305-306)
• Read the section on Polygons (p. 306-308)
• Complete the Quadrilaterals and Other Polygons Practice Set (p. 308-311)
• Read the section on Circles (p. 311-314)
• Complete the Circles Practice Set (p. 315-317)
• Read the section on Multiple Figures (p. 317-319)
• Complete the Multiple Figures Practice Set (p. 319-321)
• Read the section on Solids (p. 321-324)
• Complete the Solids Practice Set (p. 324-326)

Note: I have the 2009-10 edition, so page numbers might be different.

I have 2 days to finish this. I will go through the theory section to see if I've missed out anything. If yes, I will make a FC for it. Then I will do the practice sets. :-)

A Love Triangle

Finished Triangles yesterday. :-)

Which translates into, Geometry theory is complete!

This morning, I stared going through my Geo FCs. Want to make sure all the concepts and formulae are drilled into my head. Will practice some geo questions after that, cos it's always fun to be able to answer questions once you know your theory!!!

Yey! Very happy today!!! :-)

My Coordinates are 28° 35' N 77° 12' E

Coordinate Geometry from GMATClub's Math Book is finito! :-)

Polygons

Finished the chapter on Polygons from the GMAT Math Book at GmatClub. :-)

Fundamentally sound

Hi!

Plan for next 1 month: Go through GMAT Math book and other math resources (from GMAT Club forum) to form a complete understanding of concepts and formulae required for GMAT. Make FCs for formulae/concepts I don't already know.

31st July: Take diagnostic test (Math & Verbal) from OG11.

27th June - Circles

28th June - part of polygons

CP #10

GMAT Blue Quiz - Kaplan

UNDERSTAND EXPLANATION!!!

Question

Is a – b > 0?

(1)    a > 2b

(2)    b > a + 3

Solution

The inequality in the question stem can be manipulated so that the question reads "is a > b?"

At first glance, Statement (1) would seem to be sufficient. If a and b are both positive, and then a is certainly greater than b. But what if a and b are negative? If a = -3 and b = -2? Since -3 > -4, a would be greater than 2b; but since -2 > -3, b would be greater than a. Since Statement (1) can lead to either a yes or no answer, it is insufficient.

Manipulating the inequality in Statement (2) is more fruitful. Subtracting b and 3 from both sides gives you -3 > a-b. If that's true, then a – b is certainly less than zero. Statement (2) leads to a single, definite answer (which happens to be "no") and so is sufficient.

Kaplan Permier: Blue Quiz

Completed Kaplan Premier's Blue Quiz today. Scored an 87% overall. Got 26/30 right. Wrong - 2 CR (DOUBT IN #20 - ASK A KAPLAN INSTRUCTOR), 1 SC (idiom - as many...as) and 1 DS (ASK FRIEND!).

Speed Math: Multiplying Decimals

Went through the chapter on Multiplying Decimals. The concept is the same as any other multiplication, but one use of it is super-cool.

If you need to multiply 8 x 88, make it 8.0 x 88. Essentially, you're multiplying 80 x 88 and can just add a decimal point at the end of your answer. Super-awesome!

To Do

Hopefully will get to go through the next chapter (Multiplying Using Two Reference Numbers) today itself.

Tables upto 20!

Kaplan Diagnostic Quiz & Speed Math

Hi...

Work has kept me quite busy, so had left GMAT studies for sometime. It's time now.

Recap

Took the GMAT Diagnositc Quiz on Kaplan Premier's online companion. Scored 89% - 34 / 38 were correct answers. Got 1 wrong each in DS, PS, RC and CR. It was untimed.

To Do

While reviewing, there is 1 DS question I could not understand - will ask a friend - also, need to put it as a CP.

Another DS question took too long - must review that.

RC Strategy

In RC, writing what the para is talking about as short notes helps me. It's a PR method, but it seems to be working. It doesn't work in those passages where I have literally been unable to comprehend the meaning. To reduce the probability of that happening, I need to start taking out time to read (I used to be a voracious reader till time constrains brought my reading time down to near negligible). I also need to work on my vocab - I have Word Power Made Easy (WPME) by Norman Lewis. Maybe I should revisit it.

Speed Math

Have also been learning calculation shortcuts from Bill Handley's Speed Mathematics. It's actually quite fun and I've done a few chapters.

To Do

Do the chapter on decimal multiplication. Practise calculations.
