which books should I refer for TsEdcet biological sciences??Share some important topics to be referred help me please..am in dilemma about what to read.
There are many sources online which offer a lot of sample papers which are at par with the level of exam. You can also try to get hold of some online pdf materials and youtube lectures regarding this. I'm pretty sure there will be much sources online to get you across. Moreover try to get hold of some coaching study material, if you can. It will help you to study in an organised way.
Good luck!
