I need help for my ASAT(ALLEN) exam prep

Hi All! I am a CBSE class 10 student here! So this yr, i had made up my mind that i wanna pursue engineering and i have to crack JEE exams for that. Allen is conducting ASAT exam around march, and in TALLENTEX i did pretty bad, i didnt go through 9th class portion and thus i ended only getting 10% scholarship..... I srsly am aiming for atleast 80% scholarship.....so i googled tips on how to do well in this exam Many were saying to go thro NCERT and then foundation books....(which i still dont get what they are) but to go thro books like SCHANDS(manjeet singh and kaur) for science, ncert exemplars for math and science and rd sharma and some book for IQ(my weak spot).... ALLEN ki sample papers maine dekha, aur most of the phy qs sab 12th ke portion the... jab qs hamare level ki nai hai, kaise hum ye exam crack kar sakthe hai??? but i really feel that, most of the qs in TALLENTEX and ASAT exams which appear, are something related to ALLEN modules kyuki, definetly jo log tallentex me acche karte hai, woh log ALLEN mei 5th ya 6th class se honge.... I seriously want to know, whether do these "module" books play and imp role in their scholarship tests? And how can i elevate myself and score better? Cause in school am able to get full in chem, and get 90+ in sci and 98 or so in math par ye exams me kaise me ache ank laa sakthi hu?
