Dear Disha,

Allen has much more positive points than unacademy as Allen has experienced staff. They will provide you with their notes and will conduct your test series from time to time. You can get access to teachers easily.

But in unacademy, you can't know the teacher, can't easily access them and your doubts will not get sorted very easily.

And you can even join Allen offline whenever you like to as their online batches and offline batches are always running.

Allen's are one of the top coaching centers known so far. So, I suggest you to not miss Allen. If you want to go for unacademy in any case, unacademy provide free classes available to watch you can have a look at them too.

Moreover, most of the teachers have their youtube channels too. You can visit their respective channels and you will get access to their tricks and tips.

Infact, youtube holds many videos which are totally free which you can refer to whenever you like to in addition to Allen.

Hope this has helped you.

Good Luck :)
