Everyone please keep the questions to this strategy AND READ ALL OF THE FIRST FOUR POSTS.
Do NOT start this schedule late. You will burnout. There have already been numerous posts & threads on people starting late, trying to rush through the material, and burning out quickly.
Check the Update log in the last post for any changes.
I noticed that some people are claiming they wrote this guide to scam people out of money. Let me make this clear, I have not and will not be selling anything related to this guide. If you see a poster trying to sell books saying they wrote this schedule, do NOT buy from them. They are attempting to take your money away on false pretenses. Additionally, this guide has only been and should only be posted on SDN. I have not posted this guide anywhere else. Furthermore, SDN is the sole MCAT/medical forum I visit and the only forum where I use the screen name SN2ed. I never imagined this thread would be popular enough to warrant this kind of attention. The contents of this thread (and any other on SDN) cannot be replicated and re-hosted on any other forum, blog, or website without prior consent of both the author and SDN.
Make sure you read ALL of the opening posts, including the FAQ, before posting questions.
To begin with, check out these two threads:

MCAT and a Heavy School Workload Don't Mix: Stop rushing to take the MCAT:http://forums.studentdoctor.net/showthread.php?t=602186
Can I accomplish this schedule with a part-time job or school?
Very unlikely. I highly recommend you devote 3 months to the MCAT. There may be a few that could follow this schedule and work part-time, but chances are it would not end well. You are FAR more likely to burn out if you try to study for the MCAT using this schedule and go to school or take a part/full-time job.
Furthermore, I've yet to see a valid reason for students (ie. not non-trads) to not take the MCAT in the summer.
Will following this guide guarantee me a +30?
Sadly, there are no guarantees on the MCAT. I certainly hope it helps you, but I can't say whether or not you'll hit your target score.
Should I take the MCAT before finishing my pre-reqs?
There's no point in doing so. You have to take them anyway. Hence, you might as well go into the test with your pre-reqs completed. Yes, this includes the English pre-req.
Any tips for retakers?

Remember to check out the third and fourth post FAQ.
Anything else before I start?
CONFIDENCE. Through all of the troubles and hardships you'll face, approach everything with confidence. You must constantly attack this test. The MCAT is merely a stepping stone on your journey.
Also, this is just a guide I made up. It is my opinion on what a study schedule should resemble. I'm sure there will be people that disagree with parts of this schedule or the whole thing. This schedule can easily be adjusted for 4 months instead of 3. I don't suggest starting heavy studying 5 months+ from your test date. Keep it to 3-4 months. If you start too soon, it will be a waste of time and resources.
Remember to use the search function on these forums. Tons of questions have already been asked and answered.
Lastly, please give credit to me, SN2ed, if you post this elsewhere. I put a ton of work into it.
Materials:
- Berkeley Review (BR) General Chemistry
- BR Organic Chemistry
- Examkrackers (EK) Biology for non-detailed approach OR The Princeton Review Hyperlearning (TPR) Biology/BR Biology for a detailed approach (In the schedule, I will use EK Bio because most prefer a non-detailed approach)
- BR Bio
- BR Physics
- EK 1001 series, excluding EK 1001 Bio (i.e. do NOT buy EK 1001 Bio)
- EK Verbal 101
- TPR Hyperlearning Verbal Workbook or Berkeley Review Verbal
- AAMC Full Length (FL) #3-5 and 7-11 (AAMC #6 is not available at the moment)
You're using EK Bio for content review and BR Bio for passages. If you need more detail during in your content review, refer to BR Bio.
You can pick up the BR books from their website: http://www.berkeley-review.com/TBR/home-study.html
Also, check out the For Sale section on here: http://forums.studentdoctor.net/forumdisplay.php?f=230 All of the above, except for the AAMC FLs show up from time to time. I've regularly seen a complete BR set go for under $100 on there. Whenever you buy used, MAKE SURE THE PASSAGES ARE UNMARKED.
To buy the AAMC FLs: http://www.e-mcat.com/
Bare Minimum Set-up:
$245 for AAMC FLs (http://www.e-mcat.com/)
$240 for BR Physics, O-chem, Gen Chem, Biology (http://www.berkeley-review.com/TBR/home-study.html)
$26 for EK Verbal 101 (http://www.amazon.com/Examkrackers-MCAT101-Passages-Verbal-Reasoning/dp/1893858553)
$30 EK Bio (Amazon product ASIN 1893858626)
Prices vary on TPR Hyperlearning Verbal Workbook, search the For Sale forum on here for copies. They regularly show up. You should be able to get one for under $50.
Total = $541 + TPR Hyperlearning Verbal Workbook
Set-up with EK 1001:
$18 EK Physics 1001 (http://www.amazon.com/Examkrackers-1001-Questions-MCAT-Physics/dp/1893858189)
$20 EK O-Chem 1001 (http://www.amazon.com/Examkrackers-1001-Questions-Organic-Chemistry/dp/1893858197)
$19 EK Chem 1001 (http://www.amazon.com/Examkrackers-1001-Questions-MCAT-Chemistry/dp/1893858227)
Total = $598 + TPR Hyperlearning Verbal Workbook
Possible Book Replacements:
If you're having a hard time finding the TPR Hyperlearning Verbal Workbook, BR is an okay replacement. Well, there's not much of a choice left. Again, I HIGHLY recommend you hunt down the TPRH Verbal Workbook.
TPRH is a great choice for content review in all subjects, however, you still need the BR books and EK 101 Verbal for their practice passages. TPRH does not have enough practice passages, though the Workbooks are still great resources.
A Little Bit more about TPRH books:
If you're looking for the Science or Verbal Workbooks, your best bet is through the For Sale forum on here: http://forums.studentdoctor.net/forumdisplay.php?f=230
You can also find the full TPRH set in the For Sale. People usually sell the whole set together.
If you want the content books, they're available on Amazon.
Yes, these books are the same as the TPRH content review books. The only difference is that these books, unlike the class content review books, contain some practice passages. I believe it's 3-4 passages per chapter. It's not enough to just stick with these books and some FLs, but it's nice to have a few passages thrown in.
About the EK 1001 series:
It is a good idea to get the complete EK 1001 series. I thought they really helped me nail down my understanding of the various topics. Through using the physics especially, I found that I didn't understand some things as well as I would like. Furthermore, for whatever reason, they helped me visualize the problem in my head and made the equations intuitive to use. Too many people neglect their basic understanding which could be bolstered by EK 1001. They think they have a strong grasp, yet when those fundumentals are tested, one's weaknesses become more apparent. Plus, doing more timed practice problems is always a good thing.
The only negative for the non-bio and VR practice books is that they aren't in the right format (unless you think of them as tons of discretes). However, it is significantly easier to spot your content weaknesses with EK 1001 because they aren't passages. You don't have to worry about if you messed up due to a failure to synthesize multiple ideas or the passage was worded strangely. When you mess up on EK 1001, you know it's due to a content weakness. Lastly, this problem would be alleviated by the BR books and EK content books containing practice passages. There are also the practice tests that you will be taking.
I suggest you get the above materials 1-2 months in advance! It takes awhile to get your BR books! You don't want to be missing your materials when you're about to start this schedule. Also, older content review books are usually okay, just don't go too far back (past 5 years old).
Lastly, sign up for your MCAT as soon as possible. Seats fill up months in advance.
Timing:
- ALWAYS complete your practice problems under TIMED conditions
- For BR passages: 6-7 minutes per passage, work towards 6 minutes
- For the EK 30-minute exams….well 30 minutes
- EK 1001, except Bio series: 30 seconds to 1 minute per question
- EK Verbal 101/TPR Verbal: 6-7 minutes per passage, work towards 6 minutes
- AAMC FLs: Use their timing
Notes:
- Do NOT retake old practice material
- Thoroughly review ALL of your practice problems. Review your problems the day AFTER you take them. Don't even look at the answers until then. If there's a break day, review your problems on the day after your break.
- Remember to round like crazy for any math problem
- Always use process of elimination with your answer choices
- Before you begin this schedule, count the number of verbal practice passages (101 from EK + however many in the TPR Hyperlearning Verbal Workbook). Divide the number of passages by 70 (total days - the number of break days AND FL days). That number is the number of verbal passages you should be taking per day. I'm hoping that number breaks down to at least 3 passages per day. Ideally, you should take 4-5 verbal passages per assigned day. You do NOT take verbal passages on break days OR FL days.
- If you don't want to get the EK 1001 series, spread out the second 1/3 of BR practice passages over 2 days. Again, I recommend you get the EK 1001 books that are listed.
- If your practice test score is not within your target range after 2-3 tests, you should consider delaying. If you delay, go over your weaknesses again and complete an in-depth analysis of what went wrong.
- If you have enough money, you could adjust the schedule to fit in more practice tests. I didn't include that many to keep the cost down.
- If your test is in the morning and you're not a morning person, start getting used to waking up early when you start taking practice tests.
- Try to practice under as realistic as possible conditions when you take your practice tests. In other words: wake up early enough to be able to drive to your center; eat a meal you would eat before a test; follow the proper timing; and if you're really into it, you could even drive around for about the same time it would take you to get to your test center.
General Guidelines for Reviewing:
- Go over EVERY question. Both the ones you got right and the ones you got wrong.
- Reviewing should take 2-3 times longer than taking the timed practice problems.
- If your tests are fluctuating, it is due to the different topics on the various tests. In other words, you have some glaring weaknesses that when targeted, nail you, badly. You have to find out what those weaknesses are because they are evident by your scores. Do NOT dismiss any wrong answer as a "stupid mistake." You made that error for a reason. Go over your tests again.
- You might want to consider making a log for all of your post test results where you work through the questions below. Doing so, you'll be able to easily notice trends.
Some things to go over when reviewing:
1. Why did you get the question wrong? Why did you get the question right?
2. What question and passage types get you?
3. How is your mindset when facing a particular passage?
4. Are you stressed for time?
5. Where are your mistakes happening the most? Are they front loaded? Are they at the end? All over?
6. What was your thought process for both the questions you got right and the ones you got wrong?
7. For verbal, what was the author's mindset and main idea?
8. Did you eliminate all of the answer choices you could from first glance?
ex. You know an answer should be a positive number so you cross out all of the negative number answer choices.
9. What content areas are you weak in?
10. Why are the wrong answers wrong and the right answer right?
11. How can you improve so you don't make the same mistake again?
Hat Trick:
Get a hat and write every single MCAT PS and BS topic onto a piece of paper. Then, when you're ready to practice PS, put all the PS topics into the hat. Draw two or three pieces of paper and connect the topics together. In addition to connecting them, come up with what a passage might look like and what kind of questions you might get. If you can't do this, go back and review each of the three sections. Rinse and repeat.
The hat trick days are important because they aid you in synthesizing the various topics together. On the MCAT, you utilize this skill for every passage because MCAT passages combine topics. Furthermore, you may also discover content weaknesses that you will need to go over.

Here's a rough example using Distillation, Mendelian Genetics, and Lipids:
You are studying a Mendelian inherited recessive genetic defect of a lipid receptor. A defect in this receptor prevents the uptake lipids in the body and can cause several negative effects, such as, atherosclerosis due to fat build-up in arterial walls.
To test for the concentration of lipids in a patient's blood, you design a distillation experiment.
1. Given a couple where the male is Ll and the female is ll, what is the chance the child will have the defect?
2. What kind of solvent should you use to test the concentration of lipids?
3. What type patient would have the highest boiling point elevation?
4. If the trait exhibited incomplete dominance, which patient is likely to be Ll? Boiling point information here.
5. Which cell component requires lipids?
