How can I improve in Quant, when I practice in study room, I can able to solve 3/5 or sometimes 4/5 too. But in sectionals, I am getting the approach but cant able to do the problem, why like that? Please help me.

Don't panic while taking Sectional/Mock....the panic and hurry will worse things....select precisely which you can do and do them first....no. of attempts will increase gradually.....any question taking greater than 3 min leave and go for next....can come to it last again......atleast 50 questions of practice between a mock/sectional from weak areas
