I came across some tips online and would like to share them with my fellow NLders.
1. Put "listento" after the "www." in the URL to download the audio to a YouTube video.

2. Adding "gif" before the word "Youtube" in the URL allows you to create your own gif with the video.

3.There is a free website called "essaytyper" that lets you type a topic and it will write the paper for you in minutes

4.At an airport and need wifi? Add "?.jpg" at the end of any URL to bypass the expensive wifi and access the Internet for free.

5. 10minutesemail.com gives you a fake email address to signup for anything if you don't want to use your own email.

6.If you download a "PDF" file and you see it ends in "exe" delete it. It's a virus.

7.When you’re finished with an essay, copy and paste it into Google Translate and listen to it. It’s the easiest way to find mistakes.

BONUS
And in maths
When trying to look for percentages (ex 40% of 300) drop the 1st digit of the number and multiply by the 10s digit of the % (4 x 30 = 120)

nice

Thank you!
They ARE REALLY VERY HELPFUL TIPS.
