High scores do matter if you plan to apply for Teaching Assistantship or a Research Assistantship position. Hence practice a ton of tests and make sure to ace it.

Prepare for TOEFL along with GRE when you prepare for GRE Verbal.

Plan to take the test within two weeks of GRE exam so that you can focus purely on TOEFL after GRE exam.

TOEFL website helps you do this.

You can select some universities to which your score will be reported automatically at the end of your test.

If you plan to send your scores to more universities than the free limit, you will have to pay per extra university.

Scores can be sent to universities electronically. No need to send any hard copy scores.

From experience, we recommend nothing less than 100.

Infact, our ideal suggestion would be 100+ to 115 to be considered for TA/RA position.

Some universities do take lower scores, so is their quality and we want you to be at your best.
