There are many addons ( and games) available for the calculator. These calculator makes short work of the A level Maths and helps too with the science.

Using your phone effectively in science

It’s a camera, but better it’s a video camera, and slo-mo at that. Start recording your experiments. Use the phone to make video notes or get an app like Notetalker to record a lesson and all the slides. This makes revision a breeze.

So do you have to write up an experiment? Did the results get messed up? But did you manage to video the experiment - all the equipment is there, how it was setup, what you did, what was said. A photo of the results helps, especially with character recognition and turning results into graphs.
