Strengthening Areas of Weakness
While carefully analyzing your practice tests, there are four types of weakness to watch out for:
1. Specific quantitative skills/concepts (e.g., algebra, standard deviation, etc.)
2. Specific Verbal skills/concepts (e.g., 3-blank text completion questions, weak vocabulary, etc.)
3. Test-taking skills (time management, endurance, anxiety etc.)
4. Silly mistakes
For the first two weaknesses, the fix is straightforward: find the related lesson(s), learn the concept/skill, and answer practice questions (in the Reinforcement Activities box) to strengthen that weakness.
If your test-taking skills are the issue, then work on those. For example, you'll find a video on time anxiety reduction in the General Strategies module.
If silly mistakes are hurting your score, then you must identify and categorize these mistakes so that, during tests, you can easily spot situations in which you are prone to errors. For more on this, read the article, Avoiding Silly Misteaks on the GRE.
Finally, a great way to build your GRE skills is to ask and answer questions on the GRE Prep Club forums.
