My GMAT Study Plan

Hey

I am a newbie in the GMAT world. I have not started studying as I am still formulating the preparation plan. I plan to take the GMAT around late July- early Aug 2018. Since, there is quite some time and I m working a 9 to 5 job, I plan to take things slower than usual. Below is my tentative plan:

1) Day 0: Take the Diagnostics Test of OG under non-time bound condition and analyze the score.
2) Week 1: Go through Manhattan Foundations of GMAT Math
3) Week 2-3: Revise the Quant concepts from OG and solve practice questions
3) Week 4-7: Delve deeper into Quant using Manhattan guides 1 to 5
4) Week 8: Go through Manhattan Foundations of GMAT Verbal
4) Week 9-11: Brush the Verbal concepts from OG and try to answer practice questions.
5) Week 12-17: Take the Verbal by horns and study from Manhattan guides 6 to 9.
6)Week 8-17: Keep on revising the concepts of Quant for half an hour a day (using flash cards, if required) so that I do not forget those things in these 10 arduous weeks.
7) Week 17-19: Prepare for IR (yet to finalize the study material)
8) Week 20: Take GMAT Club Test and analyze the result, practice more in the sections where my performance in not as per the expectations.
9) Week 21-23: Solve 700-800 level questions
10) Week 23: Take GMATPrep Exam and analyze result, practice more in the sections where my performance in not as per the expectations.
11) Week 24-27: Search Internet for more practice questions and mock tests.
12) Week 28-29: Prepare for AWA
13) Week 30-31: Revision of Concepts
14) Week 32: Analysis and learnings from Error Log (I plan to keep error log from Day 0)
15) Week 33-36: Some more revision, go through questions already practiced.
16) 3 weeks cushion in case any personal or professional emergency comes up.
17) Week 40: Exam ready J

Read a lot (but exactly what? )

Does the plan sound effective?
Will OG and Manhattan series be enough to prepare? If not, what other sources should I consider?
Is the placement of IR and AWA preparation time ok? If not, where should they be ideally put?
Any help with the IR and AWA preparation material would be greatly appreciated.
Any suggestion regarding what mock tests to be taken, besides GMAT Club Test and GMATPrep Exam, is welcomed. Also, tell me how can I obtain a free subscription to them.
Please suggest me some reading material (books, magazines, newspapers) that will help me tackle the AWA and the Verbal sections more efficiently.
If you like the above plan, then please give me a kudos as I read 25 kudos would earn me free GMAT Club Test.
