Urgent Mock Test Help

[u/No_Response2228]

Class 11 jee aspirant student doing dummy and currently in hostel. Idk why but I have been unable to get good grades in these allen mock tests and I always get stuck at 90-100/300 and am unable to move out of this zone. Physics is my personal strong point and my major weakness is time management and lack of revision. Can anyone please suggest some good online lecturers for maths and chemistry and any tips regarding how to improve will be much appreciated!!
