Two labs. One loop.
Chemistry and physics, practised the way you actually learn: read a short idea, watch it move, try it yourself, then check. প্রতিটি সেকশনে একই লুপ — পড়ো → দেখো → নিজে করো → যাচাই। Your progress is saved on your own device; there is nothing to sign in to.

Chemical reactions & equations — iterative course
Empirical formula → reactions → balancing → moles → limiting reagent → percentage yield → chapter check → board questions.

Reaction visualizer
Pick reactants and watch the reaction unfold — ion movement, electron transfer, precipitate and gas bubbles, with a Bengali explanation for every reaction.

Newton’s laws, projectile motion and waves are queued behind the same loop. Request a topic and it gets prioritised.
