I dont know what to memorise instead the spec or the textbook for science, the textbook is a lot and it will take way more time and i just started my revision now But i want to have some time applying my knowledge and with other subjects .
i also realised in freesciencelessons videos they are points copied from the spec , so...
is it best to memorise the spec and understand the work or is the spec too little detail ? i'm very confused :0 , i've already started to trying to memorise the textbook and its too frustrating as i have very poor memory . also in textbooks at the end of every chapters they're chapter summaries , shall i just memorise this instead or the spec ?
