Biology -

For learning purposes: 

use Cliffnotes AP Bio, Barrons AP Bio, and Feralis Biology Notes.

Questions:

Use DAT qVault, DAT bootcamp. I found that DAT qvault is best for this subject. DAT bootcamp is closest to the real thing, but DAT qvault is slightly more difficult which prepares you better. If you've exhausted these options and still need to work on it, then go ahead and use DAT destroyer bio. 

OCHEM -

For learning purposes: 

to learn the material I used the Kaplan Blue Book, as well as the DAT destroyer reaction charts. Both are very important. I also subscribed to "Chads Ochem" videos to brush up on material I had forgotten. 

Questions:

DAT destroyer, DAT bootcamp, DAT qVault, in that order. 

Side note - Ochem is the only DAT destroyer section you should do first. This is because for all other sections, DAT destroyer is so much more difficult than the real thing that its virtually useless. 

General Chemistry: 

For learning purposes: 

Kaplan Bluebook, and Chad's Ochem. 

Questions:

DAT bootcamp, DAT qvault, DAT destroyer.

Remember DAT destroyer is just so much harder than the real thing, so I would do it last. 

Math:

For learning purposes: 

Kaplan Bluebook

Questions: 

DAT bootcamp, Math destroyer.

Perceptual Ability: 

This one is tricky. You're gonna need a variety of sources to prepare you well for this.

You need Crack DAT PAT, as well as DAT bootcamp.

DAT bootcamp is by far closest to the real thing, however it doesn't provide enough practice. It's important to note that the Crack DAT keyhole questions are different from the real thing, as well as the angles. On the real thing, the angles are significantly more difficult. It's an excellent source though for the TFE questions, as well as the cube questions. 

Reading: 

Truthfully, I didn't ~really~ prepare for this section. That being said, I'll explain my tactic that I devised for the reading section for people who can't retain what they read the first time or can't read fast - 

You are given a note sheet during the exam. First thing you should do when reading the passages is IDENTIFY KEY WORDS in every passage. WRITE THEM on the paper. For example, if you have an essay about sharks and the first paragraph is talking about fins, the second paragraph is talking about their habitats, the third paragraph talks about their conservation, then on your notebook you write 1. Fins 2. Habitat 3. Conservation. In this way, you're mapping exactly where the passage discusses the topics within. The key is to find what you're looking for much quicker, hence enhancing your ability to answer questions in a timely manner. 

GENERAL STUDY TIPS:

Always alternate between studying facts and testing yourself. You should dedicate the first week or two of wrapping your head around the material. After that, however, you should continuously be taking practice tests to gauge your performance and see where you need to improve.

Review every test you take and mark down the concepts that you got wrong and review them before you take another test.

STUDY SMART. When you study, focus on the material, don't daydream. Time is PRECIOUS. I studied for about a month studying 6-8 hours a day in the early morning when I am most able to devote my attention to the material. Each second of those hours were utilized. You may be able to study less or need to study more than this. We are all unique in terms of our science backgrounds so this may differ.

I ordered things for a reason. Go for high yield sources, sources that will most likely help you. That's why you should save all DAT destoyer sections except for Ochem and Math to the end. In short, you should order your studying around what material is most likely to come up. 

DO PAT EVERY DAY. PAT is not something you binge study for. It's inefficient to study one subject only a day. Best is to dedicate a day to 2 subjects, maybe 3 at most. But every day, do a little bit of PAT practice, maybe an hour or so. PAT is a skill. It is NOT something you can really cram. Before you know it, you'll be able to to do it very well. If you follow my advice here, and practice practice practice, there's no reason you shouldn't get a 21 or higher. 

Good luck and never give up.
