Hello !

First of all , all distance learning programs are different and suit different students. Some coaching platforms which you can try are  :

1. Resonance offers great theoretical coverage in textual material along with a number of questions which build the level of toughness gradually.
2. In Allen most of there theory is pretty summarized. They do give really good practice questions, with units divided in terms of toughness and type of questions.
3. For online you can try , TOPPR
4. KAYSONS EDUCATION
5. BYJU'S

The above listed are some institutes (not ranked) , you can try anyone of them which suits you best in terms of fees , study material , mock tests and faculties.

Hope it helps & All the best for your career :)
